Malignant Mesothelioma

Malignant mesothelioma is a cancer that affects the lining of the lung, chest cavity, or abdominal cavity. If a tumor formed in the mesothelium—special cells that protect the organs—are cancerous, the disease is called malignant mesothelioma. Malignant mesothelioma is almost always caused by workplace or non-occupational exposure to asbestos.
