Malignant mesothelioma is a rare cancer that develops in the mesothelium, the protective linings that cover various organs.
This type of cancer most commonly affects the linings of the lungs (pleura) or abdomen (peritoneum). In rare cases, mesothelioma tumors can grow in the linings of the heart (pericardium) or testes (tunica vaginalis).
The only proven cause of mesothelioma is exposure to asbestos.
