Mesothelioma is a rare form of cancer which is almost always caused by exposure to asbestos. This type of cancer happens when harmful, or malignant, cells develop in the protective lining that covers most of the body's internal organs. The most common sites for mesothelioma are in the chest or belly, where cells become abnormal in response to asbestos fibers that have embedded in the outer lining of the lungs or abdominal cavity (belly), or in the sac that surrounds the heart.
