Mesothelioma (malignant)
Alternate Names : Malignant mesothelioma
Definition
Malignant mesothelioma is an uncommon cancerous tumor of the lining of the lung and chest cavity (pleura) or lining of the abdomen (peritoneum) that is typically due to long-term asbestos exposure.
Overview, Causes, & Risk Factors
Long-term exposure to asbestos -- a fire-resistant material -- is the biggest risk factor. Asbestos was once commonly found in insulation, ceiling and roofing vinyls, cement, and automotive brake materials. Although many asbestos workers smoked, experts do not believe smoking is a cause. Malignant mesothelioma affects men more often than women. The average age at diagnosis is 60.
Cases of mesothelioma seem to be increasing worldwide.
