Malignant mesothelioma is a disease in which malignant (cancer) cells are found in the mesothelium, which is a thin layer of tissue that covers most organs in the body. Mesothelioma most commonly affects the pleura (the thin layer of tissue that lines the chest cavity and covers the lungs) or the peritoneum (the thin layer of tissue that lines the abdomen and covers most of the organs in the abdomen). This article discusses malignant mesothelioma of the pleura.
Being exposed to asbestos can affect the risk of developing malignant mesothelioma. Many people with malignant mesothelioma have worked or lived in places where they inhaled or swallowed asbestos. After being exposed to asbestos, it usually takes a long time for malignant mesothelioma to occur.
Other risk factors for malignant mesothelioma include the following:
- Living with a person who works near asbestos.
- Being exposed to a certain virus.
