Medical Report

Mesothelioma is a rare cancer that attacks the body's mesothelial cells around the organs. The mesothelium provides a protective membranous lining for the internal organs and allows moving organs (i.e. the heart and the lungs) to glide easily against adjacent structures. The names of the three regions of mesothelial cells that provide protective coating are 1) pleura, the sac which surrounds the lungs; 2) peritoneum, the lining which protects the abdominal cavity; and 3) pericardium, the sac which surrounds the heart. Three different types of mesothelioma cancer attack these three different regions.

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 settlements 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 pleuron 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 cover 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 no cancerous, 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.

Asbestos is used in over 3000 modern products and most people have suffered at least some degree of exposure to it at one point or another. Most asbestos exposure is limited to minute portions of well maintained building materials such as concrete, insulation and siding. Regular maintenance of these materials is important for preventing asbestos from degenerating into airborne fibers. Unfortunately, because asbestos is so widespread, it is impossible to compute the damage that even a small quantity can cause.

The lightweight nature of the asbestos particle facilitates airborne spreading of these deadly carcinogens. This is why most asbestos-related diseases affect the respiratory system. These are incurable diseases. Even tiny amounts of asbestos can inflict irreversible damage as symptoms usually only emerge 20 to 30 years down the road.

Mesothelioma, Asbestosis and lung cancer are consequences of prolonged asbestos exposure. Any contact with asbestos merits immediate medical consultation because treatment options and survival rates are greatly improved the earlier they’re detected. Unfortunately most asbestos-related conditions don’t show symptoms until the disease is terminally advanced. Most patients diagnosed with an asbestos-related condition rarely survive more than 18 months after diagnosis.
