What is malignant mesothelioma

Mesothelioma is a tumour which affects the protective lining of the lung or abdomen, which is known as the mesothelium.

The most common form of mesothelioma is pleural mesothelioma (the lining of the lung) as compared to peritoneal mesothelioma (the lining of the abdomen). Pleural mesotheliomas make up about 95% of mesotheliomas diagnosed in Australia.
