What Is Mesothelioma?

Mesothelioma is a rare but fatal cancer that is caused by this harmful exposure to asbestos. Mesothelioma affects the mesothelium that surrounds and protects the internal organs of the body and can affect any organ in the body including the brain, heart and reproductive organs. Pleural mesothelioma is the most common and affects the lining surrounding the lungs. This lining can become cancerous when asbestos is inhaled at toxic levels. Many times the disease is asymptomatic, though symptoms may include a persistent cough, pain in the chest area or shortness of breath.
