Types of Mesothelioma

Mesothelioma cancer affects the serous membranes that surround the major organs in the midsection of the body. Different organs can be affected by mesothelioma because the serous membranes surround the lungs, heart, abdomen and others. The most common type of mesothelioma is that which affects the lung lining, and is called pleural mesothelioma. Other types are pericardial mesothelioma, which affects the lining of the heart, and peritoneal mesothelioma, affecting the lining of the abdomen.

Mesothelioma, contrary to what many people think, is not a type of primary lung cancer. That is, mesothelioma does not originate in the lungs, but as described above, it starts in the serous membranes or lining around the lungs (or other organs). However, mesothelioma can spread to the lungs and when this occurs, it is considered to be a secondary lung cancer. Mesothelioma is also commonly referred to as an asbestos lung cancer. Technically, this is also incorrect, since mesothelioma does not originate in the lungs. Asbestosis is a type of asbestos lung disease that is often confused with mesothelioma.
