Mesothelioma prognosis

Mesothelioma is an uncommon primary tumor of the serosal lining of the pleura or peritoneum. Asbestos exposure is the most common cause of mesothelioma. Unfortunately even brief exposure to asbestos may cause mesothelioma. More than 80% of patients have a clear history of exposure to asbestos. Asbestos is the name of a group of minerals that occur naturally as masses of strong, flexible fibers that can be separated into thin threads and woven. Asbestosis exposure may occur in miners, millers, and manufacturers of asbestos products. Mesothelioma can develop some 30 to 40 years after exposure.

The mesothelioma prognosis is extremely poor with median survival time of approximately 6 to 12 months from diagnosis. Although the overall prognosis for patients with mesothelioma is poor, some patients live with the disease for a considerable period of time. Mesothelioma does not generally cause symptoms in the early stages. Symptoms of mesothelioma do not typically arise until the disease has reached the late stages.
