Pleural mesothelioma

What is pleural mesothelioma?

Pleural mesothelioma is a rare malignant tumour affecting the pleura, the lining which surrounds each lung and the chest’s internal walls. The main cause of pleural mesothelioma is exposure to asbestos, a mineral which was often used for insulation or roofing. When it is extracted or removed, asbestos releases a fine dust that, if breathed in, can cause serious health damage, such as in case of pleural mesothelioma. This condition may appear many years after exposure to asbestos.


Unfortunately the outlook for mesothelioma tends to be poor, because it doesn't usually cause any obvious symptoms until late on, when tumour cells have already spread over to other organs and tissues.
