Asbestos and Cancer

If you or a loved one has been diagnosed with mesothelioma or another asbestos related cancer, you may want to seek legal advice. Typical legal settelements can reach five million dollars.
Mesothelioma is a rare form of cancer in which malignant (cancerous) cells are found in the mesothelium, a protective sac that covers most of the body's internal organs. Most people who develop mesothelioma have worked on jobs where they inhaled asbestos particles.
What is the mesothelium?
The mesothelium is a membrane that covers and protects most of the internal organs of the body. It is composed of two layers of cells: One layer immediately surrounds the organ; the other forms a sac around it. The mesothelium produces a lubricating fluid that is released between these layers, allowing moving organs (such as the beating heart and the expanding and contracting lungs) to glide easily against adjacent structures.
The mesothelium has different names, depending on its location in the body. The peritoneum is the mesothelial tissue that covers most of the organs in the abdominal cavity. The pleura is the membrane that surrounds the lungs and lines the wall of the chest cavity. The pericardium covers and protects the heart. The mesothelial tissue surrounding the male internal reproductive organs is called the tunica vaginalis testis. The tunica serosa uteri covers the internal reproductive organs in women.
What is mesothelioma?
Mesothelioma (cancer of the mesothelium) is a disease in which cells of the mesothelium become abnormal and divide without control or order. They can invade and damage nearby tissues and organs. Cancer cells can also metastasize (spread) from their original site to other parts of the body. Most cases of mesothelioma begin in the pleura or peritoneum.
How common is mesothelioma?
Although reported incidence rates have increased in the past 20 years, mesothelioma is still a relatively rare cancer. About 2,000 new cases of mesothelioma are diagnosed in the United States each year. Mesothelioma occurs more often in men than in women and risk increases with age, but this disease can appear in either men or women at any age.
What are the risk factors for mesothelioma?
Working with asbestos is the major risk factor for mesothelioma. A history of asbestos exposure at work is reported in about 70 percent to 80 percent of all cases. However, mesothelioma has been reported in some individuals without any known exposure to asbestos.
Asbestos is the name of a group of minerals that occur naturally as masses of strong, flexible fibers that can be separated into thin threads and woven. Asbestos has been widely used in many industrial products, including cement, brake linings, roof shingles, flooring products, textiles, and insulation. If tiny asbestos particles float in the air, especially during the manufacturing process, they may be inhaled or swallowed, and can cause serious health problems. In addition to mesothelioma, exposure to asbestos increases the risk of lung cancer, asbestosis (a noncancerous, chronic lung ailment), and other cancers, such as those of the larynx and kidney.
Smoking does not appear to increase the risk of mesothelioma. However, the combination of smoking and asbestos exposure significantly increases a person's risk of developing cancer of the air passageways in the lung.

Mesothelioma - An Asbestos Related Lung Cancer
by: Jill Kane
What is Mesothelioma?
Mesothelioma is a form of cancer located in the lining of either the lungs, abdomen or the heart. These linings are thin layers of tissue covering the organ.
The pleura is the tissue covering the lungs and the wall of the chest cavity which cushions and protects the lungs. The peritoneum lines the abdominal wall and surrounds most of the organs in the abdomen. The pericardium is the tissue surrounding the heart.
Mesothelioma is a rare but very serious cancer. There are three types of mesothelioma based on the types of cancerous cells. The most common type is epithelioid and consists of 50-70% of total cases and has the best prognosis. The second type is called sarcomatoid, consists of 10-20 % of mesothelioma cases and is more unpredictable in nature. The third type of mesothelioma is called biphasic, it is a combination of the other two types and consists of 20-35% of all cases.
There are an estimated 2000-3000 new cases of mesothelioma in the United States every year. The majority of these cases begin in the chest wall (pleural mesothelioma), a few start in the abdomen (peritoneal mesothelioma) and very rare are the cases starting in the lining surrounding the heart (pericardial mesothelioma).
The pleura is a thin lining of mesothelial cells. There are two pleuras in the chest, the parietal pleura and the visceral pleura. The parietal pleura lines the chest wall including the inside of the ribs, diaphragm and pericardium. The visceral pleura covers the lungs and filters fluid to and from the chest. If the pleura becomes diseases it is not effective at eliminating fluid from the chest resulting in pleural effusion or too much fluid in the chest.
Mesothelioma is usually the result of exposure to asbestos. Most people who are diagnosed with mesothelioma have had jobs where they breathed asbestos fibers. It may take up to 60 years from the time of asbestos exposure until mesothelioma develops.
Although rare, mesothelioma is a serious form of cancer which is often in its advanced stage when a diagnosis is made. In general, prognosis for mesothelioma patient is poor, however, some patients live with the disease for a long time. As mentioned earlier, the type of mesothelioma has an impact on the prognosis, as well as, the age of the patient, how much tumor has developed and if treatment is rendered. There are many variables in evaluating a mesothelioma case, so only the patients doctor can determine the best treatment and possible prognosis on an individual basis.
