Mesothelioma Disease

Mesothelioma Disease - Mesothelioma is a rare form of cancer that can arise in the mesothelial lining of the lungs, heart or abdomen. Some cases have even been reported to develop in the lining of the testicles as well. These four types of mesothelioma are called pleural mesothelioma (lung), pericardial mesothelioma (heart), peritoneal mesothelioma (abdomen) and testicular mesothelioma.

Combined, these cancers affect 2,000 to 3,000 people in the United States each year. Receiving a diagnosis can be difficult due to the similarity of symptoms to other, more common conditions and doctors may overlook mesothelioma as a diagnosis. Another contributing factor that makes these cancers difficult to diagnose is the severe latency period of symptoms. From the time of someone's initial exposure to asbestos, the primary cause of mesothelioma, signs of development may take as long as 20 to 50 years to arise.

Mesothelioma is caused by exposure to asbestos and symptoms may not appear for as long as 20 to 40 years after exposure. Mesothelioma is a cancerous tumor of the mesothelium. The mesothelium is the tissue made up of specialized cells called mesothelial cells which line the chest cavity, abdominal cavity, and the cavity around the heart. These cells also cover the outer surface of most internal organs.

The mesothelium produces a special lubricating fluid that allows organs to move around within the body with less friction. For example, this fluid makes it easier for the lungs to move inside the chest during breathing.



The mesothelium of the chest is known as the pleura. The mesothelium of the abdomen is called the peritoneum. The mesothelium of the pericardial cavity, which is the space around the heart, is called the pericardium.

Mesothelioma is a cancer that attacks any of these mesothelial regions.
