Mesothelioma is cancer that starts in pleura or lining of the heart, lungs, and abdomen.

Factors that may increase your risk for mesothelioma include:
- Asbestos exposure — Asbestos is a chemical substance found in the environment and, at one time, used in the construction and chemical industries. Exposure to asbestos has been shown to increase a person's risk of developing certain lung cancers and mesothelioma. Many cases are thought to be caused by inhaled asbestos exposure in the environment. However, the lifetime risk of developing the disease among asbestos workers is thought to be as high as 10 percent.
- Age — Risk for mesothelioma increases with age. Adults age 45 and older are at highest risk.
- Gender — Mesothelioma is more common in men and women.
