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.
