Health Risks Of Smoking Tobacco || Health Care Solutions

About half of all Americans who keep smoking will die because of the habit. Each year more than 480,000 people in the United States die from illnesses related to tobacco use. This means each year smoking causes about 1 out of 5 deaths in the US.

• Smoking cigarettes kills more Americans than alcohol, car accidents, HIV, guns, and illegal drugs combined.
• Cigarette smokers die younger than non-smokers.
• Smoking shortens male smokers’ lives by about 12 years and female smokers’ lives by about 11 years.
• Smoking not only causes cancer. It can damage nearly every organ in the body, including the lungs, heart, blood vessels, reproductive organs, mouth, skin, eyes, and bones.

How smoking tobacco affects your cancer risk

Smoking accounts for about 30% of all cancer deaths in the United States, including about 80% of all lung cancer deaths. Lung cancer is the leading cause of cancer death in both men and women, and is one of the hardest cancers to treat.

Not only does smoking increase the risk for lung cancer, it’s also a risk factor for cancers of the:

• Mouth
• Larynx (voice box)
• Pharynx (throat)
• Esophagus (swallowing tube)
• Kidney
• Cervix
• Liver
• Bladder
• Pancreas
• Stomach
• Colon/rectum
• Myeloid leukemia

Cigarettes, cigars, pipes, and spit and other types of smokeless tobacco all cause cancer. There is no safe way to use tobacco.

Does inhaling affect the risk of cancer?

Yes. Wherever smoke touches living cells, it does harm. Even smokers who don’t inhale are breathing in large amounts of smoke that comes from their mouths and the lit end of the cigarette, cigar, or pipe. They are at risk for lung cancer and other diseases caused by secondhand smoke.

How smoking tobacco damages your lungs

Smoking damages the airways and small air sacs in your lungs. This damage starts early in smokers, and lung function continues to worsen as long as the person smokes. Still, it may take years for the problem to become noticeable enough for lung disease to be diagnosed.

Smoking makes pneumonia and asthma worse. It also causes many other lung diseases that can be nearly as bad as lung cancer.

COPD

COPD, or chronic obstructive pulmonary disease, is the name for long-term lung disease which includes both chronic bronchitis and emphysema (discussed below). The risk of COPD goes up the more you smoke and the longer you smoke. It gets worse over time, and there is no cure.

Here are some facts about COPD:

• COPD is the third leading cause of death in the United States.
• Smoking is by far the most common cause of COPD.
• More women die from COPD than men.

Noises in the chest (such as wheezing, rattling, or whistling), shortness of breath during activity, and coughing up mucus (phlegm) are some of the early signs of COPD. Over time, COPD can make it hard to breathe even at rest. The late stage is one of the most miserable of all illnesses. It makes people gasp for breath and feel as if they are drowning.

Chronic bronchitis

Chronic bronchitis is a type of COPD. It’s a disease where the airways make too much mucus, forcing the person to cough it out. It’s a common problem for smokers. The airways become inflamed (swollen) and the cough becomes chronic (long-lasting). The symptoms can get better at times, but the cough keeps coming back. Over time, the airways get blocked by scar tissue and mucus, which can lead to bad lung infections (pneumonia).

There’s no cure for chronic bronchitis, but quitting smoking can help keep symptoms under control. Quitting smoking also helps keep the damage from getting worse.

Emphysema

Emphysema is the other type of COPD. It slowly destroys a person’s ability to breathe. Normally, the lungs contain millions of tiny sacs that help oxygen get into the blood. In emphysema, the walls between the sacs break down and create larger but fewer sacs. This lowers the amount of oxygen reaching the blood. Over time, these sacs can break down to the point where a person with emphysema must work very hard to get enough air, even when at rest.

People with emphysema are at risk for many other problems linked to weak lung function, including pneumonia. In later stages of the disease, patients can only breathe comfortably with oxygen.

Emphysema cannot be cured or reversed, but it can be treated and slowed down if the person stops smoking.

Why do smokers have “smoker’s cough?”

Tobacco smoke has many chemicals and particles that irritate the airways and lungs. When a smoker inhales these substances, the body tries to get rid of them by making mucus and coughing.

The early morning smoker’s cough happens for many reasons. Normally, tiny hair-like structures (called cilia) in the airways help sweep harmful material out of the lungs. But tobacco smoke slows the sweeping action, so some of the particles in the smoke stay in the lungs and mucus stays in the airways. While a smoker sleeps (and doesn’t smoke), some cilia recover and start working again. After waking up, the smoker coughs because the lungs are trying to clear away the irritants and mucus that built up from the day before.

So-called “smoker’s cough” can be an early sign of COPD.

How smoking tobacco affects your heart and blood vessels

Smoking tobacco damages your heart and blood vessels (cardiovascular system), increasing your risk of heart disease and stroke. It’s a major cause of coronary heart disease, which can lead to a heart attack.

Smoking causes high blood pressure, lowers your ability to exercise, and makes your blood more likely to clot. It also decreases HDL (good) cholesterol levels in the blood.

Smoking is a major risk factor for peripheral arterial disease (PAD). In PAD, plaque builds up in the arteries that carry blood to the head, organs, and limbs. This increases your risk of heart disease, heart attack, and stroke.

Smoking can cause or worsen poor blood flow to the arms and legs. (This is called peripheral vascular disease or PVD). This can cause pain in the legs when walking, and may lead to open sores that don’t heal. Surgery to improve the blood flow often fails in people who keep smoking. This is why many doctors who operate on blood vessels (vascular surgeons) won’t do certain operations on patients with PVD unless they stop smoking.

How smoking tobacco can affect your sex life and reproductive system

Women

Tobacco use can damage a woman’s reproductive health. Women who smoke are more likely to have trouble getting pregnant. When they are pregnant they also tend to have problems that can hurt both mother and baby, for instance:

• Smokers are more likely to have an ectopic pregnancy (where the embryo implants outside the uterus), which can threaten the mother’s life.
• Smokers are also more likely to have early membrane ruptures and placentas that separate from the uterus too early.
• Serious bleeding, early delivery (premature birth), and emergency Caesarean section (C-section) may result from these problems.
• Smokers are more likely to have miscarriages, stillbirths, babies with cleft lip or palate, and low birth-weight babies.
• Smoking during pregnancy has also been linked to a higher risk of birth defects and sudden infant death syndrome (SIDS)

Women who smoke tend to be younger at the start of menopause than non-smokers and may have more unpleasant symptoms while going through menopause.

Men

Smoking damages the arteries, and blood flow is a key part of male erections. Male smokers have a higher risk of sexual impotence (erectile dysfunction) the more they smoke and the longer they smoke. At least one study has also linked cigar smoking to sexual impotence in men.

Smoking can also affect sperm (which reduces fertility) and increase the risk for miscarriage and birth defects.

Other ways smoking tobacco affects your health

Not all of the health problems related to smoking result in deaths. Smoking affects a smoker’s health in many ways, harming nearly every organ of the body and causing many diseases. Here are a few examples of other ways smoking tobacco affects your health:

• Increased risk of gum disease and tooth loss.
• Wounds taking longer to heal
• Decreased immune system function
• Increased risk of type 2 diabetes
• Decreased sense of smell and taste
• Premature aging of the skin
• Bad breath and stained teeth
• Increased risk for cataracts (clouding of the lenses of the eyes)
• Lower bone density (thinner bones), which means a higher risk for broken bones, including hip fracture
• Higher risk of developing rheumatoid arthritis
• Increased risk for age-related macular degeneration, which can cause blindness
• Increased risk of peptic ulcers

Many of the health problems linked to smoking can steal away a person’s quality of life long before death. Smoking-related illness can make it harder for a person to breathe, get around, work, or play. Quitting smoking, especially at younger ages, can reduce smoking-related disability.

Kids who smoke have smoking-related health problems

Smoking causes serious health problems in children and teens. The most serious is nicotine addiction, which leads to long-term tobacco use. Over time, smokers then develop the health problems discussed above, and often at younger ages.

Children and teens who smoke regularly tend to have more health problems than kids who don’t, such as:

• Coughing spells
• Shortness of breath, even when not exercising
• Wheezing or gasping
• More frequent headaches
• Increased phlegm (mucus)
• Respiratory illnesses that are worse and happen more often
• Worse cold and flu symptoms
• Reduced physical fitness
• Poor lung growth and function, which increases COPD risk

Tobacco use is linked to other harmful behaviors in teens

Research has shown that teen tobacco users are more likely to use alcohol and illegal drugs than are non-users. Cigarette smokers are also more likely to get into fights, carry weapons, attempt suicide, suffer from mental health problems such as depression, and engage in high-risk sexual behaviors. This doesn’t necessarily mean that tobacco use caused these behaviors, but they’re more common in teens who use tobacco.

Risk Factors for Bone Cancer

A risk factor is anything that affects your chance of getting a disease such as cancer. Different cancers have different risk factors. For example, exposing skin to strong sunlight is a risk factor for skin cancer. Smoking is a risk factor for cancers of the lung, mouth, larynx, bladder, kidney, and several other organs. But having a risk factor, or even several, does not mean that you will get the disease. Most people with bone cancers do not have any apparent risk factors.

Genetic disorders

A very small number of bone cancers (especially osteosarcomas) appear to be hereditary and are caused by defects (mutations) in certain genes. Retinoblastoma is a rare eye cancer in children that can be hereditary. The inherited form of retinoblastoma is caused by a mutation (abnormal copy) of the RB1 gene. Those with this mutation also have an increased risk of developing bone or soft tissue sarcomas. Also, if radiation therapy is used to treat the retinoblastoma, the risk of osteosarcoma in the bones around the eye is even higher.

Finally, there are families with several members who have developed osteosarcoma without inherited changes in any of the known genes. The gene defects that may cause cancers in these families haven’t been discovered yet.

Chondrosarcomas

Multiple exostoses (sometimes called multiple osteochondromas) syndrome is an inherited condition that causes many bumps on a person’s bones. These bumps are made mostly of cartilage. They can be painful and deform and/or fracture bones. This disorder is caused by a mutation in any one of the 3 genes EXT1, EXT2, or EXT3. Patients with this condition have an increased risk of chondrosarcoma.

An enchondroma is a benign cartilage tumor that grows into the bone. People who get many of these tumors have a condition called multiple enchondromatosis. They have an increased risk of developing chondrosarcomas.

Chordomas

Chordomas seem to run in some families. The genes responsible have not yet been found, but familial chordoma has been linked to changes on chromosome 7.

Patients with the inherited syndrome tuberous sclerosis, which can be caused by defects (mutations) in either of the genes TSC1 and TSC2, seem to have a high risk of chordomas during childhood.

Paget disease

Paget disease is a benign (non-cancerous) but pre-cancerous condition that affects one or more bones. It results in formation of abnormal bone tissue and occurs mostly in people older than 50. Affected bones are heavy, thick, and brittle. They are weaker than normal bones and more likely to fracture (break). Most of the time, Paget disease is not life threatening. Bone cancer (usually osteosarcoma) develops in about 1% of those with Paget disease, usually when many bones are affected.

Radiation

Bones that have been exposed to ionizing radiation may also have a higher risk of developing bone cancer. A typical x-ray of a bone is not dangerous, but exposure to large doses of radiation does pose a risk. For example, radiation therapy to treat cancer can cause a new cancer to develop in one of the bones in the treatment area. Being treated when you are younger and/or being treated with higher doses of radiation (usually over 60 Gy) increases your risk of developing bone cancer.

Exposure to radioactive materials such as radium and strontium can also cause bone cancer because these minerals build up in bones.

Non-ionizing radiation, like microwaves, electromagnetic fields from power lines, cellular phones, and household appliances, does not increase bone cancer risk.

Bone marrow transplantation
Osteosarcoma has been reported in a few patients who have undergone bone marrow (stem cell) transplantation.

Injuries

People have wondered if injury to a bone can cause cancer. This has never been proven. Many people with bone cancer remember having hurt that part of their bone. Most doctors believe that these injuries did not cause the cancer. Instead, the cancer caused people to remember the incident or that the injury drew their attention to that bone, making them notice a problem that had already been present for some time.

Quick Review of the Alkaline Diet for Weight Loss

t's the ultimate fitness mantra of many celebs. People swear by its benefits. So, what's the hype all about? The alkaline diet, also known as the acid ash diet, is known for being a natural diet. It can promote weight loss, and some claim the diet can prevent even cancer. Does it work? Below are some of the aspects you need to know.

The Dos and Don'ts:

Let's start by saying that the alkaline diet is completely natural, and therefore, it is surely better than some of the fad diets that we all know about. If you are on this diet, your meals will be all about fruits, veggies and soy products. Some nuts, seeds and lentils are allowed, while you have to skip most of the common grains, dairy products, eggs and poultry. Red meat is also banned on the list. Thankfully, there are a good number of credible cookbooks that may come handy. Also, most books on the diet suggest to avoid alcohol and caffeine. This is also a gluten-free diet, so wheat is not allowed, but keep an eye on the labels because a lot of packaged foods do have gluten. You can also include vitamin enhanced water or alkaline water in your plan.

Will You Lose Weight?

Yes, you will lose weight in a healthy way with the alkaline diet, simply because the diet is clean and free of processed foods, carbohydrates, and gluten. However, you need to understand the process of weight loss is not because of the reason claimed. Alkaline diet says that eating foods and drinking beverages can change the pH score of your body, which isn't true. Human blood is slightly alkaline, while the stomach is high acidic. This is because the acids in the stomach help in digesting food. However, nothing you eat can affect your blood pH considerably. If weight loss is your only motto, the alkaline diet is a good place to start, but do not expected miracles.

Other Points to Note:

A lot of critics have talked about the lack of focus on exercise. In fact, the alkaline diet doesn't say anything about exercise at all. For comprehensive and sustainable weight loss and other health benefits, an active lifestyle is equally important. Researchers are also not sure of the other long list of other claims made, although limited studies have shown some positive results with regards to eating low-acid producing foods and beverages. It is also important to understand that this is not some sort of miracle diet. It would require considerable effort, and most of the foods that you are otherwise used to must be avoided completely. If you are someone who has been surviving on hamburgers, bacon and English breakfast, you need to think for a while before considering the diet. However, you can always try one of the handbooks or cookbooks to learn more about cooking alkaline meals at home, which can save money.

Check online now to find more on alkaline diet, and if you have any chronic health condition, consult your physician first.

Does UV radiation cause cancer?

Yes. In fact, most skin cancers are a direct result of exposure to the UV rays in sunlight. Both basal cell and squamous cell cancers (the most common types of skin cancer) tend to be found on sun-exposed parts of the body, and their occurrence is typically related to lifetime sun exposure. The risk of  melanoma, a more serious but less common type of skin cancer, is also related to sun exposure, although perhaps not as strongly. Skin cancer has also been linked to exposure to some artificial sources of UV rays.

Studies in people

Sun exposure

Basal and squamous cell skin cancer: Many observational studies have found that basal and squamous cell skin cancers are linked to certain behaviors that put people in the sun, as well as a number of markers of sun exposure, such as:

• Spending time in the sun for recreation (including going to the beach)
• Spending a lot of time in the sun in a swimsuit
• Living in an area with a high amount of sun
• Having had serious sunburns in the past (with more sunburns linked to a higher risk)
• Having signs of sun damage to the skin, such as liver spots, actinic keratoses (rough skin patches that can be precancerous), and solar elastosis (thickened, dry, wrinkled skin caused by sun exposure) on the neck

Melanoma: Observational studies have also found links between certain behaviors and markers of sun exposure and melanoma of the skin, including:

• Activities that lead to “intermittent sun exposure,” like sunbathing, water sports, and taking vacations in sunny places
• Previous sunburns
• Signs of sun damage to the skin, such as liver spots, actinic keratoses, and solar elastosis

Other cancers: Because UV radiation does not penetrate deeply into the body, it would not be expected to cause cancer in internal organs, and most research has not found such links. However, some studies have shown possible links to some other cancers, including:

• Merkel cell carcinoma (a less common type of skin cancer)
• Cancer of the lip
• Some types of eye cancer, such as  melanoma of the eye and squamous cell carcinoma of the conjunctiva

Artificial sources of UV rays

Indoor tanning: Studies have found that people who use tanning beds (or booths) have a higher risk of skin cancer, including melanoma and squamous and basal cell skin cancers. The risk of melanoma is higher if the person started indoor tanning before age 30 or 35, and the risk of basal and squamous cell skin cancer is higher if indoor tanning started before age 20 or 25.

Welding and metal work: Some studies have suggested that welders and sheet metal workers might have a higher risk of melanoma of the eye.

Phototherapy: People exposed to UVA as a treatment for skin conditions such as psoriasis (as a part of PUVA therapy) have an increased risk of squamous cell skin cancers.

Treatment of skin conditions with UVB alone (not combined with PUVA) has not been linked to an increased risk of cancer.

Studies in the lab

Studies of cells

Studies of cells in lab dishes and test tubes have shown that sunlight and simulated sunlight (for example, from xenon or xenon-mercury arc lamps) can cause DNA damage (mutations).

Studies in animals

Exposure of mice, rats, and some other lab animals to sunlight and artificial sources of UV rays has been shown to lead to skin cancers. Most of these cancers have been squamous cell carcinomas. Some exposed animals have also developed cancers of the eye (affecting the cornea and conjunctiva).

No type of UV radiation has been shown to be safe – cancers have developed after exposure to UVA (alone), UVB (alone), and UVC (alone).

What expert agencies say

Several national and international agencies study different substances in the environment to determine if they can cause cancer. (A substance that causes cancer or helps cancer grow is called a carcinogen.) The American Cancer Society looks to these organizations to evaluate the risks based on evidence from laboratory, animal, and human research studies.

Based on animal and human evidence like the examples above, several expert agencies have evaluated the cancer-causing nature of UV radiation.

The International Agency for Research on Cancer (IARC) is part of the World Health Organization (WHO). Its major goal is to identify causes of cancer. Based on the data available, IARC classifies UV radiation as “carcinogenic to humans.”

The National Toxicology Program (NTP) is formed from parts of several different US government agencies, including the National Institutes of Health (NIH), the Centers for Disease Control and Prevention (CDC), and the Food and Drug Administration (FDA). The NTP has classified UV radiation as “known to be a human carcinogen.”

What about tanning beds?

Some people think that getting UV rays from tanning beds is a safe way to get a tan, but this isn’t true.

IARC classifies the use of UV-emitting tanning devices as “carcinogenic to humans.” This includes sunlamps and sunbeds (tanning beds).

The NTP has stated that exposure to sunlamps or sunbeds is “known to be a human carcinogen.”

The US Food and Drug Administration (FDA), which now refers to all UV lamps used for tanning as “sunlamps,” requires them to carry a label that states, “Attention: This sunlamp product should not be used on persons under the age of 18 years.” The FDA also requires that user instructions and sales materials directed at consumers (including catalogs, specification sheets, descriptive brochures, and webpages) carry the following statements:

• Contraindication: This product is contraindicated for use on persons under the age of 18 years.
• Contraindication: This product must not be used if skin lesions or open wounds are present.
• Warning: This product should not be used on individuals who have had skin cancer or have a family history of skin cancer.
• Warning: Persons repeatedly exposed to UV radiation should be regularly evaluated for skin cancer.

Weight Loss - Creating Your Personal Weight Loss Plan

Has needing to lose weight been on your mind? If so, you are in the process of following a weight loss plan or not doing anything at all. There is no middle ground. If the latter applies to you, it pays to take a moment to consider why you are not making an effort to reach your goals. Is it because of a lack of guidance and instruction? Surely you want to lose weight; otherwise, you would not be thinking about it. Perhaps the need to lose weight is more significant than your desire to get lean. Often this is the case for many adults, who realize being overweight is more problematic than it initially seems.

You may need some guidance. So let's talk about some tips for creating a weight loss program that will work for you. If you are already making an effort, the following might still be of use to you...

1. Outline your objectives

 First, you must outline your goals. Don't focus so much on the specifics. It is not nearly as important to set how much weight you ought to lose, as it is focusing on the process itself. It is better to focus on losing weight generally, not how much.

Have your "why" adequately figured out before you begin.

2. Eat well

Not surprisingly, it is vital to eat well when starting a weight loss program. Your food choices matter, more than you may think.

It becomes especially important to eat the right carbohydrates if you have high blood sugar. In any case, it will probably do you well to eat more fruits and vegetables than you already do, and eat a healthy balance of proteins and fats. They are all important.

3. Mind your portion sizes

Your portion sizes are just as important as your food choices. Even if you are selecting healthy carbohydrates such as brown rice and sweet potatoes, you can still overeat and losing weight will then be much harder.

Counting calories helps, but is too tedious for most people. By eating slowly, you will have a better idea of how much you should be eating. Always stop eating before you feel full, and don't hesitate to feel hungry for a part of your day.

4. Begin exercising

 If you have not already, start exercising. It will help, no matter which exercise program you chose. Even walking will help get the job done.

5. Anticipate setbacks

Setbacks will occur: know you will not make weekly progress forever. You will stall eventually. You will get frustrated. Relax and make adjustments if needed. Don't stress, and be patient: weight loss requires patience more than anything.

Lastly, remember to make your weight loss program your own. What works for other people will not necessarily work for you. Feel free to experiment with different diets and exercise plans. But know you will have to discover what yields the best results for you and your body.

Although managing your disease can be very challenging, Type 2 diabetes is not a condition you must just live with. You can make simple changes to your daily routine and lower both your weight and your blood sugar levels. Hang in there, the longer you do it, the easier it gets

What Is Breast Cancer?

Breast cancer starts when cells in the breast begin to grow out of control. These cells usually form a tumor that can often be seen on an x-ray or felt as a lump. The tumor is malignant (cancer) if the cells can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body. Breast cancer occurs almost entirely in women, but men can get breast cancer, too.

Cells in nearly any part of the body can become cancer and can spread to other areas. To learn more about cancer and how all cancers start and spread, see Cancer Basics.

Where breast cancer starts

Breast cancers can start from different parts of the breast. Most breast cancers begin in the ducts that carry milk to the nipple (ductal cancers). Some start in the glands that make breast milk (lobular cancers). There are also other types of breast cancer that are less common.

A small number of cancers start in other tissues in the breast. These cancers are called sarcomas and lymphomas and are not really thought of as breast cancers.

Although many types of breast cancer can cause a lump in the breast, not all do.  Many breast cancers are found on screening mammograms which can detect cancers at an earlier stage, often before they can be felt, and before symptoms develop. There are other symptoms of breast cancer you should watch for and report to a health care provider.

It’s also important to understand that most breast lumps are benign and not cancer (malignant). Non-cancerous breast tumors are abnormal growths, but they do not spread outside of the breast and they are not life threatening. But some benign breast lumps can increase a woman's risk of getting breast cancer. Any breast lump or change needs to be checked by a health care professional to determine if it is benign or malignant (cancer) and if it might affect your future cancer risk.

How breast cancer spreads

Breast cancer can spread when the cancer cells get into the blood or lymph system and are carried to other parts of the body.

The lymph system is a network of lymph (or lymphatic) vessels found throughout the body that connects lymph nodes (small bean-shaped collections of immune system cells). The clear fluid inside the lymph vessels, called lymph, contains tissue by-products and waste material, as well as immune system cells. The lymph vessels carry lymph fluid away from the breast. In the case of breast cancer, cancer cells can enter those lymph vessels and start to grow in lymph nodes. Most of the lymph vessels of the breast drain into:

• Lymph nodes under the arm (axillary nodes)
• Lymph nodes around the collar bone (supraclavicular [above the collar bone] and infraclavicular [below the collar bone] lymph nodes)
• Lymph nodes inside the chest near the breast bone (internal mammary lymph nodes)

If cancer cells have spread to your lymph nodes, there is a higher chance that the cells could have traveled through the lymph system and spread (metastasized) to other parts of your body. The more lymph nodes with breast cancer cells, the more likely it is that the cancer may be found in other organs. Because of this, finding cancer in one or more lymph nodes often affects your treatment plan. Usually, you will need surgery to remove one or more lymph nodes to know whether the cancer has spread.

Still, not all women with cancer cells in their lymph nodes develop metastases, and some women with no cancer cells in their lymph nodes develop metastases later

How Is Malignant Mesothelioma Diagnosed?

Mesothelioma is most often diagnosed after a person goes to a doctor because of symptoms they are having. If there is a reason to suspect you might have mesothelioma, your doctor will examine you and use one or more tests to find out. Symptoms might suggest that the problem could be mesothelioma, but tests will be needed to confirm the diagnosis.

Medical history and physical exam

If you have any signs or symptoms that suggest you might have mesothelioma, your doctor will want to get your medical history to learn about your symptoms and possible risk factors, especially asbestos exposure.

A physical exam can provide information about possible signs of mesothelioma and other health problems. Pleural mesothelioma can cause fluid to build up around the lungs in the chest (called a pleural effusion). In cases of peritoneal mesothelioma, fluid can build up in the abdomen (called ascites). In pericardial mesothelioma, fluid builds up in the sac around the heart (called a pericardial effusion). Rarely, mesothelioma can develop in the groin and look like a hernia. All of these might be found during a physical exam, such as when the doctor listens to these areas with a stethoscope or taps on the chest or abdomen.

If mesothelioma is a possibility, tests will be needed to make sure. These might include imaging tests, blood tests, and other procedures.

Imaging tests

Imaging tests use x-rays, radioactive particles, sound waves, or magnetic fields to create pictures of the inside of your body. Imaging tests might be done for a number of reasons, such as:

• To look at suspicious areas that might be cancer
• To learn how far cancer has spread
• To help determine if treatment is working

People thought to have mesothelioma may have one or more of these tests.

Chest x-ray

This is often the first test done if someone has symptoms such as a constant cough or shortness of breath. Findings that might suggest mesothelioma include an abnormal thickening of the pleura, calcium deposits on the pleura, fluid in the space between the lungs and the chest wall, or changes in the lungs themselves as a result of asbestos exposure.

Computed tomography (CT) scan

The CT scan uses x-rays to make detailed cross-sectional images of your body. Instead of taking one picture, like a regular x-ray, a CT scanner takes many pictures as it rotates around you while you are lying on a narrow table. A computer then combines these into images of slices of the body.

CT scans are often used to help look for mesothelioma and to determine the exact location of the cancer. They can also help determine the stage (extent) of the cancer. For example, they can show if the cancer has spread to other organs. This can help determine if surgery might be a treatment option. Finally, CT scans can also be used to learn if treatment such as chemotherapy is shrinking or slowing the growth of the cancer.

A CT scanner has been described as a large donut, with a narrow table that slides in and out of the middle opening. You will need to lie still on the table while the scan is being done. CT scans take longer than regular x-rays, and you might feel a bit confined by the ring while the pictures are being taken.

Before the test, you might have to drink a liquid called oral contrast. This helps outline the intestine so that certain areas are not mistaken for tumors. You might also need an IV (intravenous) line through which a different kind of contrast is injected. This helps better outline structures in your body. The injection can cause some flushing (redness and warm feeling). Some people are allergic and get hives or, rarely, more serious reactions like trouble breathing and low blood pressure. Be sure to tell the doctor if you have any allergies (especially to iodine or shellfish) or have ever had a reaction to any contrast material used for x-rays.

Echocardiogram

This test uses sound waves to look at the heart. It may be done if your doctor suspects that you have fluid around your heart (a pericardial effusion). This test can also tell how well the heart is working. For the most common version of this test, you lie on a table while a technician moves an instrument called a transducer over the skin on your chest. A gel is often put on the skin first.

Positron emission tomography (PET) scan

For a PET scan, a radioactive substance (usually a type of sugar related to glucose, known as FDG) is injected into the blood. The amount of radioactivity used is very low. Because cancer cells grow quickly, they absorb more of the sugar than most other cells. After waiting about an hour, you lie on a table in the PET scanner for about 30 minutes while a special camera creates a picture of areas of radioactivity in the body.

The picture from a PET scan is not as detailed as a CT or MRI scan, but it can provide helpful information about whether abnormal areas seen on these tests are likely to be cancerous or not. For example, it can give the doctor a better idea of whether a thickening of the pleura or peritoneum seen on a CT scan is more likely cancer or merely scar tissue. If you have been diagnosed with mesothelioma, your doctor may use this test to see if the cancer has spread to lymph nodes or other parts of the body. A PET scan can also be useful if your doctor thinks the cancer may have spread but doesn’t know where.

Some machines can do both a PET and CT scan at the same time (PET/CT scan). This lets the doctor compare areas of higher radioactivity on the PET scan with the more detailed appearance of that area on the CT.

Magnetic resonance imaging (MRI) scan

Like CT scans, MRI scans make detailed images of the body’s soft tissues. But MRI scans use radio waves and strong magnets instead of x-rays. A contrast material called gadolinium is often injected into a vein before the scan to better show details. This contrast is different than the one used for CT scans, so being allergic to one doesn’t mean you are allergic to the other.

MRI scans can sometimes help show the exact location and extent of a tumor since they provide very detailed images of soft tissues. For mesotheliomas, they may be useful in looking at the diaphragm (the thin band of muscle below the lungs that helps us breathe), a possible site of cancer spread.

MRI scans take longer than CT scans – often up to an hour. You may have to lie inside a narrow tube, which can upset people with a fear of enclosed spaces. Special, more open MRI machines may be an option in some cases. The MRI machine makes buzzing and clicking noises that you might find disturbing. Some places will give you earplugs to help block this out.

Blood tests

Blood levels of certain substances are often higher in people with mesothelioma:

• Osteopontin
• Soluble mesothelin-related peptides (SMRPs), detected with the MesoMark® test

Mesothelioma can’t be diagnosed with these blood tests alone, but high levels of these substances can make the diagnosis more likely. These tests are not routinely used in most doctors’ offices because of their limited value.

Tests of fluid and tissue samples

Symptoms and test results may strongly suggest that a person has mesothelioma, but the actual diagnosis is made by removing cells from an abnormal area and looking at them under a microscope. This is known as a biopsy. It can be done in different ways, depending on the situation.

Removing fluid for testing

If there is a buildup of fluid in part of the body that might be due to mesothelioma, a sample of this fluid can be removed by inserting a thin, hollow needle through the skin and into the fluid. Numbing medicine is used on the skin before the needle is inserted. This may be done in a doctor’s office or in the hospital. Sometimes ultrasound (or an echocardiogram) is used to guide the needle. These tests use sound waves to see inside the body.

This procedure has different names depending on where the fluid is:

• Thoracentesis removes fluid from the chest.
• Paracentesis removes fluid from the abdomen.
• Pericardiocentesis removes fluid from the sac around the heart.

The fluid is then tested for its chemical makeup and is looked at under a microscope to see if it contains cancer cells. If cancer cells are found, special tests might be done to see if the cancer is a mesothelioma, a lung cancer, or another type of cancer.

Even if no cancer cells are found in the fluid, a person might still have cancer. In many cases, doctors need to get an actual sample of the mesothelium (the pleura, peritoneum, or pericardium) to determine if a person has mesothelioma.

Needle biopsies

Suspected tumors in the chest are sometimes sampled by needle biopsy. A long, hollow needle is passed through the skin in the chest between the ribs and into the pleura. Imaging tests such as CT scans are used to guide the needle into the tumor so that small samples can be removed to be looked at under the microscope. This is often done using just numbing medicine.

Needle biopsy can also be used to get samples of the lymph nodes in the space between the lungs to see if the cancer has spread there (see “Endobronchial ultrasound needle biopsy”).

Needle biopsies do not require a surgical incision or overnight hospital stay. But the downside is that sometimes the samples removed are not big enough to make an accurate diagnosis. This is especially true for mesothelioma. A more invasive biopsy method may be needed.

There is a slight chance that the needle could put a small hole in the lung during the biopsy. This can cause air to build up in the space between the lung and the chest wall (known as a pneumothorax). A small pneumothorax might not cause any symptoms. It may only be seen on an x-ray done after the biopsy, and it will often go away on its own. But a larger pneumothorax can make part of a lung collapse and might need to be treated. The treatment is placement of a small tube (a catheter) through the skin and into the space between the lungs. The tube is used to suck the air out in order to re-expand the lung and is left in place for a short time.

Endoscopic biopsies

Endoscopic biopsy is commonly used to diagnose mesothelioma. An endoscope is a thin, tube-like instrument used to look inside the body. It has a light and a lens (or tiny video camera) on the end for viewing and often has a tool to remove tissue samples. Endoscopes have different names depending on the part of the body where they’re used.

Thoracoscopy: This procedure uses an endoscope called a thoracoscope to look at areas inside the chest. It can be used to look at the pleura and take tissue samples for biopsies.

Thoracoscopy is done in the operating room while you are under general anesthesia (in a deep sleep). The doctor inserts the thoracoscope through one or more small cuts made in the chest wall to look at the space between the lungs and the chest wall. This lets the doctor see possible areas of cancer and remove small pieces of tissue to look at under the microscope. The doctor can also sample lymph nodes and fluid and see if a tumor is growing into nearby tissues or organs.

Thoracoscopy can also be used as part of a procedure to keep fluid from building up in the chest. This is called pleurodesis and is discussed in Palliative Procedures Used for Malignant Mesothelioma.

Laparoscopy: For this test, the doctor uses an endoscope called a laparoscope to look inside the abdomen and biopsy any peritoneal tumors. This is done in the operating room while you are under general anesthesia (in a deep sleep). The laparoscope is inserted into the abdomen through small cuts on the front of the abdomen.

Mediastinoscopy: If imaging tests such as a CT scan suggest that the cancer might have spread to the lymph nodes between the lungs, the doctor may want to sample some of them to see if they really contain cancer. The area between the lungs is called the mediastinum, and looking at it with an endoscope is called mediastinoscopy. This is done in an operating room while you are under general anesthesia (in a deep sleep).

A small cut is made in the front of the neck above the breastbone (sternum) and a thin, hollow, lighted tube (called a mediastinoscope) is inserted behind the sternum. Special instruments can be passed through this tube to take tissue samples from the lymph nodes along the windpipe and the major bronchial tube areas.

Lung cancers often spread to lymph nodes, but mesotheliomas do this less often. Testing the lymph nodes can help show whether a cancer is still localized or if it has started to spread, which might affect treatment options. It can also sometimes help tell lung cancers from mesotheliomas.Patients with mesothelioma don’t need to have bronchoscopy to see if tumors are in their airways (because that isn’t where tumors from mesothelioma are found). Instead, bronchoscopy may be used to biopsy lymph nodes near the lungs (instead of using mediastinoscopy).

Endobronchial ultrasound needle biopsy: For this test, a bronchoscope (a long, thin, flexible, fiber-optic tube) with an ultrasound device at its tip is passed down the throat and into the windpipe. The ultrasound lets the doctor see the nearby lymph nodes. A hollow needle is then passed down the bronchoscope and through the airway wall into the nodes to take biopsy samples. This procedure may be done with either general anesthesia (where you are asleep), or with numbing medicine (local anesthesia) and light sedation.

Open surgical biopsy

Sometimes, endoscopic biopsies aren’t enough to make a diagnosis, so more invasive procedures are needed. By making an incision in the chest (thoracotomy) or an incision in the abdomen (laparotomy) the surgeon can remove a larger sample of tumor or, sometimes, remove the entire tumor.

Testing the samples in the lab

No matter how they’re obtained, all biopsy and fluid samples are sent to the pathology lab. There, a doctor will look at them under a microscope and test them to find out if they contain cancer cells (and if so, what type of cancer it is).

It’s often hard to diagnose mesothelioma by looking at cells from fluid samples. It can even be hard to diagnose mesothelioma with tissue from small needle biopsies. Under the microscope, mesothelioma can often look like other types of cancer. For example, pleural mesothelioma can resemble some types of lung cancer, and peritoneal mesothelioma in women may look like some cancers of the ovaries.

For this reason, special lab tests are often done to help tell mesothelioma from some other cancers. To learn about some of the tests that might be done on tissue samples, see Testing Biopsy and Cytology Specimens for Cancer.

If mesothelioma is diagnosed, the doctor will also determine what type of mesothelioma it is, based on the patterns of cells seen in the microscope. Most mesotheliomas are classified as either epithelioid, sarcomatoid, or mixed/biphasic.

Pulmonary function tests

If mesothelioma has been diagnosed, pulmonary function tests (PFTs) may be done to see how well your lungs are working. This is especially important if surgery might be an option to treat the cancer. Surgery often requires removing part or all of a lung, so it’s important to know how well the lungs are working to start with. These tests can give the surgeon an idea of whether surgery may be an option, and if so, how much lung can safely be removed safely.

There are a few different types of PFTs, but they all basically have you breathe in and out through a tube connected to a machine that measures your lung function.
