The tissue that lines your lungs, stomach, heart and other organs, is called mesothelioma. Mesothelioma is the cancer of that tissue. This is a rare but serious type of cancer. It usually starts in the lungs, but can also start in the stomach or other organs. Most people who develop mesothelioma have worked on jobs where they breathe asbestos particles. Between being asbestos and illness, it may take a long time - from 30 to 50 years. Treatment includes surgery, radiation, chemotherapy or all three. nih: National Cancer Institute.
