Mesothelioma is nothing but a cancer of mesothelium. It affects the abdominal cavity, chest cavity and the region surrounding the heart. It is basically the covering structure of most of the internal organs of the body. Mesothelioma is typically difficult to diagnose and treat due to its uncommon nature.

Cancer is basically excess growth of cell of particular organ or tissue. Here the triggering factor is exposure to asbestos, a material formerly present in many work environments. That’s why it is also called asbestos lung cancer.
