Mesothelioma

Mesothelioma is a rare form of cancer affecting the mesothelium, which is a membrane that covers and protects most of the internal organs of the body. In most cases, it begins in the pleura (the lining around the lungs) or peritoneum (the lining around the abdomen). The cancer is typically caused by asbestos exposure. A history of asbestos exposure at work is reported in about 70 to 80 percent of all cases of the disease. Standard treatment options include surgery, chemotherapy, and radiation therapy.
