The cancers that spread in the mesothelium tissues is called cancer Mesothelioma. It is the name of tissue that forms lining of different body organs such as heart, lungs, abdomen and reproductive organs. Peritoneal membrane is the lining around abdominal organs, pleural membrane is the lining around lungs and the lining around heart is called pericardium and these linings perform two functions. By producing a lubricating fluid it allows the smooth movement of the internal organs which protect the internal organs. These cancers affect these membranes and the names of the cancers depend on the tissue or linings they affect. Peritoneal mesothelioma, pleural mesothelioma and pericardial mesothelioma are the names of cancers of linings of abdomen, lungs and heart, respectively. The most common of all mesothelioma cancers is Pleural mesothelioma which is found in 70 % patients of this disease while 10% to 20% suffer from peritoneal mesothelioma and the third type pericardial mesothelioma, is rare.

The symptoms of these cancers are same as of other common diseases since it makes diagnosis mesothelioma cancers a difficult task. Some of the symptoms of peritoneal mesothelioma are pain and swelling in abdomen, weakness, loss of weight, loss of appetite and nausea. While the symptoms of pleural mesothelioma are persistent cough, difficulty in breathing, weight loss, loss of appetite, weakness, chest pains, lower back pains and difficulty in swallowing.

The history of mesothelioma cancers goes back to as far back as 1900s and it took about 60 years to gather sufficient information about this cancer mesothelioma. Experts could conclude that exposure to asbestos particles is the reason behind the disease by the end of sixth decade of last century.
