Mesothelioma

Also called Pleural mesothelioma

Mesothelioma is a type of cancer that develops in the thin layer of tissue covering many organs, most often the lining of the lungs (pleural mesothelioma) and sometimes the lining of the tummy (peritoneal mesothelioma). It is almost always caused by breathing in asbestos fibres, often 20 to 50 years before symptoms start.

What it is

It is usually found at a late stage and is difficult to cure.

Treatment can include immunotherapy, chemotherapy, radiotherapy and draining fluid to help breathing. Compensation may be available for people exposed to asbestos at work.
