Malignant Pleural Mesothelioma

Malignant pleural mesothelioma is a rare disease in which cancer cells develop in the protective sac covering the lungs. The main risk factor for this condition is exposure to asbestos. Possible signs include shortness of breath and pain under the rib cage. It can be difficult to distinguish between malignant pleural mesothelioma and lung cancer, so it may be necessary to examine the inside of the chest to confirm the diagnosis.
