Mesothelioma is a rare form of cancer that is characteristically and specifically linked to asbestos exposure.

Asbestos exposure is a well-established cause of several respiratory and pleural diseases, including asbestosis (a type of lung fibrosis), lung cancer, pleural plaques, pleural thickening, and mesothelioma. While asbestosis is the fibrotic disease caused by asbestos, mesothelioma is a distinct malignancy that is particularly strongly and specifically associated with asbestos exposure compared to other causes.

Mesothelioma primarily affects the lining of the lungs (pleura), but can also occur in the lining of the abdomen (peritoneum), heart (pericardium), or testes. There is a long latency period, often decades, between asbestos exposure and the development of mesothelioma. Liver fibrosis has different causes (e.g., viral hepatitis, alcohol). Pleural effusion can have many causes, including but not limited to asbestos exposure. While asbestos causes lung fibrosis (asbestosis), mesothelioma is considered the most specific and characteristic *malignancy* linked to it.
