The Disease Itself:

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.

That is a form of cancer that almost always caused by previous exposure to the asbestos (a fireproof material). In this disease, malignant cells develop in the mesothelium, a defensive lining that cover most of the body's internal organs. Its most common site is the pleura (exterior lining are pulmonary and chest cavity), but it can also happen in the peritoneum (the lining of the abdominal cavity) or the pericardium (a sac that surrounds the heart).

Most of people that develop mesothelioma worked in jobs where they inhaled particles of asbestos, or have been exposed to dust of asbestos and fibre in other ways, like by washing the clothes of family member that worked with asbestos, or by renovation of home using asbestos cement products. There isn't any association between mesothelioma and smokes.

Types of the disease

Pleural: This variation of the disease attacks the longs and the body's respiratory areas. The malignant cancer attacks the cells and the lining (known as the pleura) of the lungs and ribs.
Mesothelioma cells Peritoneal: This form of the cancer disease attacks the lining of the abdomen. This type of cancer is caused by asbestos exposuring, and it affects the lining that protects the contents of the abdomen which also provides a lubricating fluid to enable the organs moving and working properly.
