Mesothelioma What is Mesothelioma? Mesothelioma (also known as ‘diffuse’ or ‘malignant’ Mesothelioma) is a form of cancer, which affects the thin membranes which line the chest (pleural mesothelioma). Less commonly it can affect the linings of the abdomen (peritoneal mesothelioma). It may also surround the organs found within these cavities for example the heart, lung and intestines.

How is Mesothelioma diagnosed? Early diagnosis is difficult and in most cases the first obvious sign is sudden breathlessness caused by an accumulation of fluid in the pleural space - a pleural effusion. It may be accompanied by other symptoms such as chest pain. Scans and X-rays can provide strong evidence to support the diagnosis especially coupled with a history of asbestos exposure. However, other diseases can produce these symptoms and to be certain of a correct diagnosis more investigations often need to be carried out. Scans, Fluid taken for laboratory examination, possibly needle biopsy or keyhole surgery to take a biopsy (a small sample of tissue) are likely to be carried out to help with the confirmation of the diagnosis. These tests and results may take several weeks to complete.
