The lining around the abdominal organs is known as the peritoneal membrane. Lining around the lungs is called pleura while the lining around the heart is called pericardium.These fillings fulfill two functions. They protect the internal organs by producing a lubricating fluid and allow the fluidity of the movement of the internal organs. Mesothelioma cancers are the cancers that affect these membranes. The names of cancers depend on the tissue or the linings they affect. Peritoneal mesothelioma, pleural mesothelioma and pericardial mesothelioma are the names of cancers of abdomen, lung and heart coatings, respectively.
Pleural mesothelioma is the most common of all mesothelioma cancers and occurs in 70% of mesothelioma patients.

JC Wagner was the first researcher to report 32 cases of mesothelioma cancers and confirmed his association with asbestos exposure.One finding alarming about mesothelioma cancers is his prolonged latency period. These cancers can remain asymptomatic in the body even up to 50 years.
