Malignant mesothelioma can also be classified by different cancer cell types, each of which tends to behave differently. There are three classifications assigned to mesothelioma cell types.
Epithelial Mesothelioma is the most common cell type and accounts for approximately 50-75% percent of all diagnosed cases each year. These cells are uniform in shape, with an elongated pattern that makes them easily distinguishable when viewed under high magnification. These cancers are adenocarcinomas, malignancies which are more commonly associated with pure lung cancers as opposed to cancers of the mesothelium.
Sarcomatoid mesothelioma is a less common cell type, accounting for between 7 and 20% of diagnosed cases each year. These cells grow forth out of supportive structures, such as muscles and bones.
Biphasic mesotheliomas are those with a mix of epithelial and sarcomatoid cell types. Treatment options do not vary greatly between cell types, but often sarcomatoid mesotheliomas are more difficult to treat as a result of the surrounding affected tissues from which they spread.
Thoracoscopy and the use of special stains can be helpful in identifying cellular classifications, though obtaining adequate tissue samples often require more invasive surgeries.

Mesothelioma Latency Period
The term latency period is used to describe the period of time between exposure to a potential disease-causing agent and the time the disease becomes apparent. According to most experts, in the case of mesothelioma the latency period ranges from 20 to 50 years after initial exposure to asbestos occurred, though there have been instances when the time period was shorter or longer.
Due to the long latency period associated with the cancer, those exposed to asbestos during the 1950s, '60s and '70s are beginning to demonstrate mesothelioma symptoms today, decades after they were exposed to asbestos.
Living During the Latency Period
While no one should spend their days dwelling on the fact that they could someday develop an asbestos-related disease, there are some things that can be done to aid in early diagnosis if mesothelioma is indeed present.
The most notable development in the last few years is the mesothelioma blood test known as Mesomark. Approved by the FDA in 2007, this simple test measures a particular cancer biomarker and can catch mesothelioma in the early stages of development. The blood test is not available everywhere but if you wish to undergo testing, asking your doctor where you may take advantage of the test may aid in early detection.
Those exposed to asbestos run the risk of developing asbestosis? or mesothelioma and may wish to schedule yearly chest X-rays to check for any suspicious signs of disease. If a doctor determines there may be a concern after the X-ray, further imaging tests such as CT scans or MRIs may be recommended. A biopsy may also be requested to test for the presence of cancerous cells.

Varying Latency Periods
A number of studies have been conducted on the specifics of the length of latency periods among those exposed to asbestos.
In the case of mesothelioma, evidence has indicated that high exposure for short periods of time might be more damaging than low exposure for many years. For example, Deborah Reeve, a New York City paramedic and first responder at the site of the World Trade Center attacks in 2001, passed away from mesothelioma in 2006, just five years after her exposure to asbestos from the events on September 11. Deborah had symptoms of the disease as early as 2003 and was diagnosed with mesothelioma in 2004.
Numerous studies on asbestosis agree that more than 90 percent of individuals who were exposed to asbestos for 40 years or more will develop the disease. For those who worked with the toxic mineral for 20-30 years, the rate is about 75 percent. Those who experienced 10-19 years of exposure have an incidence level of about 10 to 15 percent. These numbers may also vary according to the level of asbestos someone is exposed to on a daily basis.
For example, shipbuilders of the mid-20th century were nearly always surrounded by asbestos as were many construction workers. Those groups have tended to develop asbestosis sooner than those who worked in other industries where the levels may not have been as high.

Stages of Mesothelioma Cancer
Medical professionals currently use three different mesothelioma-staging systems to diagnose and treat pleural mesothelioma. Each system measures different variables including the extent of the cancer, lymph node involvement, metastasis, and more.
1. Butchart System is the oldest and most commonly used mesothelioma cancer staging system and is primarily based on the extent of the tumor mass. Butchart System divides mesothelioma into four stages:
- Stage I – Mesothelioma cancer is seen in the right or left side of the chest area, or pleura cavity, and may also be found in the diaphragm.
- Stage II – Mesothelioma cancer has invaded the chest lining and reaches the esophagus, heart, or pleura on both sides. Lymph nodes may also be affected.
- Stage III – Mesothelioma cancer has passed the diaphragm and entered the abdominal cavity or peritoneum. Lymph nodes beyond the chest may also be affected.
- Stage IV – Mesothelioma cancer has spread through the bloodstream to other organs
2. TNM System is a more recent system used to stage mesothelioma by considering variables such as the tumor size and spread, lymph node involvement, and metastasis. In the TNM system, the disease is divided into four stages:
- Stage I – Mesothelioma cancer is in the right or left chest cavity and may have spread to the pericardium, diaphragm, or lung on the same side. Lymph nodes are not affected.
- Stage II – Mesothelioma cancer has spread from one side of the chest to a lymph node near the lung on the same side. The disease may have also spread to the lung, diaphragm, or pericardium on the same side.
- Stage III – Mesothelioma cancer has entered the chest wall, muscle, heart, esophagus, ribs, and vital organs in the pleural cavity on the same side. Lymph nodes may or may not be affected on the side of the tumor.
- Stage IV – Mesothelioma cancer has spread to the lymph nodes in the chest area on the other side of the tumor, or has spread to the pleural cavity or lung on the other side, or has reached organs in the abdominal area or neck. Any metastasis is involved in the fourth stage.
3. Brigham System is the latest mesothelioma cancer staging system and is based on tumor resectability (ability to surgically remove) and lymph node status. The Brigham system is divided into five stages:
- Stage I – Mesothelioma cancer is resectable and lymph nodes are not involved
- Stage II – Mesothelioma cancer is resectable, but lymph nodes are involved
- Stage III – Mesothelioma cancer is unresectable and has spread to the chest wall, diaphragm, heart, or abdominal area. Lymph nodes may or may not be involved.
- Stage IV – Distant metastatic mesothelioma cancer
)
Mesothelioma Life Expectancy
By the time most people who develop mesothelioma actually have the condition diagnosed, the mesothelioma prognosis is usually pretty bad. The average life expectancy for mesothelioma patients at the time of diagnosis is about one year. Several factors can influence that though. One of the major ones is the stage to which the mesothelioma has advanced.
Here are the stages of malignant pleural mesothelioma as defined in the TNM system, which is also known as the International Mesothelioma Interest Group staging system:
- Stage 1 – Only one layer of the pleura is affected by mesothelioma. It may have spread to the pericardium or diaphragm.
- Stage 2 – both layers of the pleura are affected by mesothelioma on only one side of the body.
- Stage 3 – The mesothelioma has spread to the chest wall, esophagus, or lymph nodes on one side of the body.
- Stage 4 – Mesothelioma has spread to other organs, such as the brain, bones, lymph nodes, liver, or to the other side of the body.
There are other staging systems, but the TNM is rapidly gaining favor as the standard. There is no staging system for pericardial mesothelioma.
Life Expectancy by Stage
The following prognoses are meant to give you a general idea of life expectancy at diagnosis, which varies case-to-case. Catching mesothelioma in its early stages can mean the difference between living another 5 years (or even being cured completely) and dying in a few months. Consult your physician for more information about your specific case.
- Stage 1 – 50% will live another 5 years if treated aggressively
- Stage 2 – Average life expectancy: 2-4 years
- Stage 3 – Average life expectancy: 6-8 months
- Stage 4 – Average life expectancy: less than 6 months
Those who are involved in clinical trials for mesothelioma tend to survive longer on average than those who are not. There are many clinical trials going on right now.

Mesothelioma Diagnosis
Mesothelioma patients are typically diagnosed within three to six months of their first visit to a doctor with complaints about breathing problems or chest and abdominal pain. The first step involved in diagnosis is providing a full and accurate medical history to your doctor, including details about current and past health concerns, as well as the types of symptoms you are currently experiencing.
It is important to mention any possible exposure to asbestos. Without revealing this fact, your doctor may not consider asbestos-related diseases in his or her examination. Next, patients will undergo a physical examination where a doctor will examine causes for any types of symptoms being displayed. In most cases, the doctor's next step will be to recommend further testing.
Mesothelioma Diagnostic Tests
If your doctor suspects an asbestos-related disease such as mesothelioma, the next step in the diagnostic process includes testing to confirm the presence of mesothelioma, determine the location, size and type of cancer involved, and determine whether the asbestos cancer has spread to other parts of the body. This will often involve imaging tests such as:
- Chest X-ray: This is the most commonly used imaging test for the diagnosis of mesothelioma. Almost all diagnoses will involve an X-ray, but a more sophisticated test may follow.
- CT Scan: This is an X-ray-like procedure in which several X-ray pictures are taken and combined with a computer to produce a detailed image of body tissues. If you undergo a CT scan, you may be given an intravenous injection of dye that helps produce more detailed images.
- PET Scan: A glucose solution is administered through intravenous injection and a scanner is used to spot deposits of cancer cells. Malignant cells take up and use sugars more quickly than normal cells, so they can be easily distinguished using this procedure.
- MRI Scan: A combination of radio waves and a strong magnetic field is used to create detailed three-dimensional images that can be carefully examined by a radiologist.
Fluid and Tissue Tests
These tests, also known as biopsy tests, involve collecting small samples of fluid or tissue and checking them for the presence of cancer cells. Such tests include:
- Fine Needle Aspiration: Mesothelioma cancers cause fluid to build up in affected locations, such as in the pleural membrane
. During a fine needle aspiration, a doctor will remove a fluid sample using a very long, thin and hollow needle.
- Thoracoscopy: Thoracoscopy is used in cases where pleural or pericardial mesothelioma is suspected. During this procedure, a very small incision is made in the chest wall and a sample of tissue is removed.
- Bronchoscopy and Laparoscopy: These procedures are similar to the thoracoscopy, but are performed on different parts of the body. The bronchoscopy is used to view the trachea and airway, while the laparoscopy is used to remove samples of peritoneal tissue.
- Mediastinoscopy: This procedure is used to view lymph nodes in the chest and neck, to determine if cancer has spread from its point of origin.

Mesothelioma Causes
An overwhelming body of scientific and medical evidence has proven that malignant mesothelioma is caused by asbestos exposure. Currently, there is no other proven cause for this disease.
Asbestos is a naturally-occurring fibrous mineral that was widely used in industrial, commercial, and domestic products throughout the twentieth century. Asbestos was touted for its durability, fire resistance, and excellent insulating properties, and was used in several thousand different manufactured "asbestos products," including construction materials, household appliances, and brake linings. Because asbestos use was so widespread, millions of Americans have been exposed to the toxic material, which has led to the development of malignant mesothelioma among thousands of Americans.
Unfortunately many companies knowingly manufactured asbestos-contaminated products, placing millions at risk of asbestos exposure. Today, as more and more people are being diagnosed with asbestos-related illnesses, the companies can be ordered to provide compensation to patients with an asbestos-related disease. Extensive information about mesothelioma and legal options available to patients is available by filling out this form or calling 800-615-2270 and speaking with an educated patient and family advocate.
How Does Asbestos Exposure Cause Mesothelioma?
Internal organs and body cavities are covered by a thin tissue membrane called the mesothelium. This lining covers the thoracic cavity (where it is called the pleura), the heart sac (where it is known as the pericardium), and the abdominal cavity (where it is called the peritoneum). The mesothelium offers both support and protection for organs and body cavities and provides a source of lubrication that helps organ function and health.
Mesothelioma develops in the linings of organs and body cavities, typically in the pleura, pericardium, or peritoneum. In very rare cases, mesothelioma may develop in the lining of the testicles, known as the tunica vaginalis.
The exact method by which asbestos causes mesothelioma is still being researched, but medical professionals offer four different theories:
- Asbestos causes irritation and inflammation of mesothelial cells, which results in irreversible scarring, cellular damage, and eventually cancer.
- Asbestos fibers enter cells and disrupt the function of cellular structures that are essential for normal cell division, causing cellular changes that lead to cancer.
- Asbestos causes the production of free radicals. These molecules damage DNA, and cause cells to mutate and become cancerous.
- The presence of asbestos causes cells to produce oncoproteins. These molecules cause mesothelial cells to ignore normal cellular division restraints, and this can lead to the development of cancer.
The element that ties each theory together is the fact that asbestos results in cellular damage, which causes cells to lose control over their own cycles of normal division and begin dividing uncontrollably. Healthy cells follow cycles of cell division that ensure tissues and organs do not grow beyond normal size - in cancer cells, these restraints are lost.
In cases of mesothelioma, the result is that membranes in the affected location begin to thicken, and fluid builds up in the spaces between membrane layers. As cancer cells continue to divide and pile on top of one another, tumors begin to form. The uncontrolled division of cancer cells results in the impaired function of the body's organs and systems (primarily due to factors such as internal pressure caused by the growth of tumors, and the reduction of essential nutrients for organs).
Are There Any Other Causes of Mesothelioma?
Cancer doctors and research scientists have not been able to directly prove any other causes of mesothelioma other than asbestos exposure. They do know, however, that smoking can aggravate a less serious asbestos-related disease, such as asbestosis, and prompt the formation of tumors and the onset of mesothelioma. Additionally, asbestos exposure and smoking has a synergistic affect that can increase a person's risk of developing lung cancer by as much as 84 times or more. For this reason, those who have been exposed to asbestos on a regular basis are highly advised not to smoke.
Mesothelioma is caused by long-term, repeated exposure to asbestos fibers. The disease is generally fund in four different forms: pleural, peritoneal, pericardial, and testicular. In each case, the cancer develops in mesothelial cells, which form the membranous linings that surround and protect organs. The different names for each type of mesothelioma refer to the point of origin of the caoncer.
Mesothelial membranes are made up of two different layers, called the parietal and visceral layers. Parietal layers are outer layers, and these typically cover large areas such as the chest cavity (in the case of pleural and pericardial membranes) and the abdominal cavity (as in the case of peritoneal membranes). Visceral layers are those that cover organs such as the lungs and heart. Mesothelioma develops in these membranes when asbestos fibers become trapped in the spaces between mesothelial cells.
Mesothelioma is a particularly aggressive type of asbestos cancer, and is highly resistant to treatment, resulting in very high mortality rates and poor prognosis for people diagnosed with the disease. In general, pleural mesothelioma responds more positively to treatment, particularly if the disease is diagnosed early. However, all forms of mesothelioma are difficult to diagnose, and unfortunately, it is common for the disease to be diagnosed too late for treatment to be effective.
The type of mesothelioma a patient is diagnosed with will invariably determine the treatment plan suggested by their doctor. A myriad of treatment options are available for patients diagnosed with all types of mesothelioma and a comprehensive packet detailing the options will be provided overnight to those interested who fill out this form.
Pleural Mesothelioma
Pleural mesothelioma develops in the mesothelial lining of the lungs, which is known as the pleura. About 75 percent of all mesothelioma cases are pleural.
Symptoms of pleural mesothelioma include difficulty swallowing, a persistent dry cough, persistent chest pain, or pain when breathing, and difficulty breathing even when resting. These mesothelioma symptoms result from pressure on the lungs and respiratory system, caused by thickening of the pleural membrane and fluid build-up between membrane layers. As the cancer advances, lumps may develop under the skin of the chest.
Diagnosis of pleural mesothelioma involves imaging tests such as chest x-rays, MRIs, and CT scans, and may also include biopsies that remove tissue and fluid to test for the presence of cancer cells. These tests also help determine the stage of the cancer and the options available for treatment. Generally, patients in stage one and two mesothelioma are good candidates for surgery, whereas patients in stages three and four have more limited treatment options, and may only be able to receive palliative treatments.
Peritoneal Mesothelioma
Peritoneal mesothelioma develops in the peritoneal lining of the abdominal cavity. This is a relatively rare form of mesothelioma; approximately 10 to 20 percent of all mesothelioma cases are peritoneal in nature.
Symptoms of peritoneal mesothelioma include pain or swelling of the abdomen, changes in bowel habits (such as constipation or diarrhea), unexplained weight loss, and nausea or vomiting. These symptoms are caused by thickening of peritoneal membranes and fluid build-up, which puts pressure on internal organs and prevents normal function of some organs. As the cancer advances, people with peritoneal mesothelioma may notice lumps developing under the skin of the abdomen.
Diagnosis of peritoneal mesothelioma involves imaging tests such as CT scans and MRIs, as well as biopsies of fluid and tissue to detect the presence of mesothelioma cells. There is currently no recognized staging process for peritoneal mesothelioma.
Peritoneal mesothelioma is problematic in terms of treatment, because the cancer can spread quickly throughout the peritoneum and often metastasizes more quickly than other types of mesothelioma. In some cases surgery is possible, but this is typically a palliative treatment option.
Pericardial Mesothelioma
Pericardial mesothelioma develops in the membrane that surrounds the heart, also known as the pericardium. This is a very rare form of mesothelioma, occurring in only 1 to 5 percent of cases. This form of mesothelioma is also very difficult to treat.
Symptoms of pericardial mesothelioma include irregular heartbeat or palpitations, chest pain, and difficulty breathing. These are caused by the pressure put on the heart by the build-up of fluid in the spaces between pericardial membrane layers.
It is very rare for pericardial mesothelioma to be diagnosed early enough for any form of treatment to be effective, and pericardial mesothelioma patients typically have an extremely poor prognosis. In very rare cases, the cancer may be diagnosed early enough for surgery to have a positive effect; however, the proximity of this cancer to the heart makes such surgery a high-risk mesothelioma treatment option.
Testicular Mesothelioma
Testicular mesothelioma is the rarest of all mesothelioma cancers, as less than one hundred cases have been recorded. This type of mesothelioma develops in the lining that surrounds the testicles, known as the tunica vaginalis.
Due to the extreme rarity of testicular mesothelioma, very little has been noted about its symptoms and the treatment options available. Often, the disease is not diagnosed until patients notice the appearance of testicular lumps. In some cases, surgery for an unrelated condition such as a hernia leads to the detection of testicular mesothelioma.
If the primary tumor has developed in the testicles, treatment involves removal of part or the entire affected testicle, followed by chemotherapy or radiation therapy. In many cases the testicular tumor is secondary, and the primary cancer is located in the peritoneum. In these cases, treatment follows established patterns for peritoneal mesothelioma in addition to removal of testicular tumors.

Mesothelioma Prevention
For individuals who have worked with asbestos for many years, the discussion of mesothelioma prevention seems to be a moot point. Many who have been exposed to asbestos believe it's already too late to talk about ways to avoid developing mesothelioma. They think the affect of asbestos on the lungs has already manifested itself and there's no escaping the threat of developing the disease. However, past asbestos exposure is not the only factor people should worry about because the possibility of being exposed today is just one mistake away.
Asbestos was used in literally thousands of products throughout much of the twentieth century. Many of those items, particularly building products, are still in homes, offices, and factories across the country. Workers in specific industries can still encounter asbestos as well, including those who work in shipyards, power plants, chemical plants, or in the railroad and automotive industry.
Prevention at Work
In the past, the majority of workers had no idea that asbestos exposure could lead to the contraction of serious diseases. Today, however, most individuals are aware of the dangers, especially if they work in an industry that traditionally made use of the toxic substance. Regardless of the knowledge that is now available, not everyone takes the proper precautions that are needed to prevent exposure.
Preventing asbestos exposure and the risk of contracting mesothelioma at work can be accomplished through a few simple precautions. First of all, protective gear should be worn any time the presence of asbestos is suspected. Secondly, any clothes worn while working with asbestos should be left at the site. Wearing asbestos-covered clothes outside the work area could subject others to unwanted exposure. When dealing with asbestos, proper abatement methods should also be followed to ensure complete safety.
Prevention in the Home
Most people don't encounter asbestos simply by walking around their home even if there is asbestos inside. Asbestos exposure usually occurs during home renovation projects because do-it-yourself projects can catch non-professionals off guard. Some of the in-home items that may contain asbestos include:
Attic insulation
Roof shingles and tar
Drywall and drywall glue
Floor tiles
Popcorn ceilings
Joint compounds
Wrapping on pipes and electrical wires
Asbestos that is already damaged or may be crumbling because of age is referred to as "friable" asbestos. This kind of asbestos is especially dangerous because the toxic fibers that make up asbestos can easily circulate through the air become inhaled. Anyone performing any type of serious renovation work on a home built prior to 1980 should always wear protective gear.
Mesothelioma Prevention After Exposure
Individuals who have already been exposed to asbestos, but have not developed an asbestos-related disease should be diligent about monitoring their health on a regular basis. This can be done in a few different ways:
Mesothelioma blood test - A simple blood test that can detect mesothelioma before its symptoms appear was approved by the FDA. Dubbed Mesomark, this test can be administered in a doctor's office. Find out if your doctor has access to the test and be sure to be tested annually.
Imaging and other tests - Asbestos-exposed individuals can also be monitored via a diagnostic imaging test such as an x-ray, or by means of a pulmonary function test, which measures how well the lungs are working. These should also be done annually.
Also, anyone who has been exposed to asbestos and has not yet developed an asbestos-related disease should not smoke. Smoking greatly increases the possibility of developing such a disease. In addition, those who have asbestosis and continue to smoke run a much higher risk of developing mesothelioma.

Joint compound
Roofing tar
Brake pads
Fireproofing
Pipes
Insulation
Countertops
Floor tiles
Textured wall and ceiling coatings
If these items are intact, they usually present little to no health hazards. However, if they are damaged or "friable," they should be removed from the house immediately. Removal should be done by a licensed abatement company, as this is the best way to protect you and your family from asbestos exposure.
On-the-Job Prevention
Workers in particular industries may still be at risk for exposure to asbestos. Those in the construction industry, for example, may encounter old buildings that contain asbestos. It is necessary to take great care in protecting yourself if the presence of asbestos is suspected, which includes wearing proper gear to avoid inhalation.
Monitoring Your Health
If you have already been exposed to asbestos, regularly monitoring your health is essential in order to catch the early warning signs of disease. Remember, treatment options are greater the earlier the disease is diagnosed. It is important to have regular chest x-rays and pulmonary function tests, even if you are experiencing no symptoms of disease.
In addition, if you have been exposed to asbestos in the past, you may be able to reduce your chances of developing mesothelioma by not smoking. Studies show that smoking damages the lungs and can affect the risk of developing mesothelioma. Anyone who does develop an asbestos-related disease should stop smoking immediately.
For individuals who have worked with asbestos for many years, the discussion of mesothelioma prevention seems to be a moot point. Many who have been exposed to asbestos believe it's already too late to talk about ways to avoid developing mesothelioma. They think the affect of asbestos on the lungs has already manifested itself and there's no escaping the threat of developing the disease. However, past asbestos exposure is not the only factor people should worry about because the possibility of being exposed today is just one mistake away.
Asbestos was used in literally thousands of products throughout much of the twentieth century. Many of those items, particularly building products, are still in homes, offices, and factories across the country. Workers in specific industries can still encounter asbestos as well, including those who work in shipyards, power plants, chemical plants, or in the railroad and automotive industry.
Prevention at Work
In the past, the majority of workers had no idea that asbestos exposure could lead to the contraction of serious diseases. Today, however, most individuals are aware of the dangers, especially if they work in an industry that traditionally made use of the toxic substance. Regardless of the knowledge that is now available, not everyone takes the proper precautions that are needed to prevent exposure.
Preventing asbestos exposure and the risk of contracting mesothelioma at work can be accomplished through a few simple precautions. First of all, protective gear should be worn any time the presence of asbestos is suspected. Secondly, any clothes worn while working with asbestos should be left at the site. Wearing asbestos-covered clothes outside the work area could subject others to unwanted exposure. When dealing with asbestos, proper abatement methods should also be followed to ensure complete safety.
Prevention in the Home
Most people don't encounter asbestos simply by walking around their home even if there is asbestos inside. Asbestos exposure usually occurs during home renovation projects because do-it-yourself projects can catch non-professionals off guard. Some of the in-home items that may contain asbestos include:
Attic insulation
Roof shingles and tar
Drywall and drywall glue
Floor tiles
Popcorn ceilings
Joint compounds
Wrapping on pipes and electrical wires
Asbestos that is already damaged or may be crumbling because of age is referred to as "friable" asbestos. This kind of asbestos is especially dangerous because the toxic fibers that make up asbestos can easily circulate through the air become inhaled. Anyone performing any type of serious renovation work on a home built prior to 1980 should always wear protective gear.
Mesothelioma Prevention After Exposure
Individuals who have already been exposed to asbestos, but have not developed an asbestos-related disease should be diligent about monitoring their health on a regular basis. This can be done in a few different ways:
Mesothelioma blood test - A simple blood test that can detect mesothelioma before its symptoms appear was approved by the FDA. Dubbed Mesomark, this test can be administered in a doctor's office. Find out if your doctor has access to the test and be sure to be tested annually.
Imaging and other tests - Asbestos-exposed individuals can also be monitored via a diagnostic imaging test such as an x-ray, or by means of a pulmonary function test, which measures how well the lungs are working. These should also be done annually.
Also, anyone who has been exposed to asbestos and has not yet developed an asbestos-related disease should not smoke. Smoking greatly increases the possibility of developing such a disease. In addition, those who have asbestosis and continue to smoke run a much higher risk of developing mesothelioma.
Joint compound
Roofing tar
Brake pads
Fireproofing
Pipes
Insulation
Countertops
Floor tiles
Textured wall and ceiling coatings
If these items are intact, they usually present little to no health hazards. However, if they are damaged or "friable," they should be removed from the house immediately. Removal should be done by a licensed abatement company, as this is the best way to protect you and your family from asbestos exposure.
On-the-Job Prevention
Workers in particular industries may still be at risk for exposure to asbestos. Those in the construction industry, for example, may encounter old buildings that contain asbestos. It is necessary to take great care in protecting yourself if the presence of asbestos is suspected, which includes wearing proper gear to avoid inhalation.
Monitoring Your Health
If you have already been exposed to asbestos, regularly monitoring your health is essential in order to catch the early warning signs of disease. Remember, treatment options are greater the earlier the disease is diagnosed. It is important to have regular chest x-rays and pulmonary function tests, even if you are experiencing no symptoms of disease.
In addition, if you have been exposed to asbestos in the past, you may be able to reduce your chances of developing mesothelioma by not smoking. Studies show that smoking damages the lungs and can affect the risk of developing mesothelioma. Anyone who does develop an asbestos-related disease should stop smoking immediately.
Diagnosis mesothelioma is a scary subject you don't want to talk or hear about. It is a heart wrenching news for you and your family. But fortunatelly, over the years scientist has been able through research to detect and treat mesothelioma. There are a lots sites online filled with helpful informations. There are also support groups and help mechanisms put in place for every stage of this dreadful disease. Mesothelioma disgnosis does not guaranteed a grim prognisis; therefore, in most cases early detection of the disease as with any cancer is important so that it can be treated early.
Simply put, the diagnosis of mesothelioma is the first step on a road to discovery. There are many websites to aid in the publics’ research of mesothelioma and the warning signs that lead to early diagnosis and subsequently the blessing of early treatment. It is common to treat a diagnosis of mesothelioma with surgery and chemotherapy or surgery, chemotherapy and radiation. Mesothelioma is also known as the asbestos cancer. Mesothelioma shows subtle variations from asbestosis or asbestos pleural disease. Regardless it is highly recommended if you have worked around asbestos in anyway or form that you are checked for mesothelioma on a regular basis. Early diagnosis is imperative. Some of the varied warning signs include shortness of breath as well as pain in the lower back or pain at the side of the chest. Others signs may include hoarseness, difficulty swallowing or sweating and fevers.
Prognosis defers significantly among people that have been disgnosed with mesothelioma and this depends on a number of factors. These causes have a significant impact on the speed of recovery; the size of the cancer, what part of the body it is found, and how far it has spread. And also, how the cancer cells looks under the microscope, and their respond to treatment as well as

Malignant mesothelioma is cancer that starts in the cells that line certain parts of the body, especially the chest, belly (abdomen), and heart. The lining formed by these cells is called mesothelium. These cells protect organs by making a special fluid that allows the organs to move. For instance, this fluid makes it easier for the lungs to move during breathing.
Tumors of the mesothelium can be benign or they can be cancerous. A cancerous tumor of the mesothelium is called a malignant mesothelioma, but this is often shortened to just mesothelioma. The information that follows covers only those tumors that are cancer.
Main types of mesothelioma
There are 3 main types of mesotheliomas based on how the cells look under a microscope.
epithelioid: This is the most common type. It tends to have a better outlook (prognosis) than the other types.
sarcomatoid (fibrous): About 1 or 2 out of 10 mesotheliomas are of this type.
mixed (biphasic): This type has features of the 2 types above. About 3 or 4 out of 10 mesotheliomas are the mixed type.
About 3 out of 4 mesotheliomas start in the chest cavity. These are called pleural mesotheliomas. Another 10%-20% begin in the abdomen (belly). These are called peritoneal mesotheliomas. Those starting around the heart are very rare. This cancer can also start in the tissue around the testicles, but this is also very rare.
