Mesothelioma is a fairly rare cancer that can lead to a malignant tumor and is associated with prior exposure to asbestos. The exposure could have been 20 to even 50 years ago and only now will symptoms start to appear. Mesothelioma can develop in mesothelial cells in the pleura, pericardium, and peritoneum.
The pleura is the outer lining that surrounds your lungs. This lining lets your lungs have flexibility when you breathe in or out. After exposure to asbestos, a tumor may eventually develop in this area creating what is known as pleural mesothelioma. This is common if asbestos material has been inhaled either by mining it or working in a factory that uses it in a product.
