The peritoneal mesothelioma is cancer of the mesothelioma that develops in the peritoneum, or the membrane that lines the abdomen. It is much less common than the pleural mesothelioma (but more common than pericardial and testicular) and is the cause of around 600 cases in the united States annually. Men tend to get it a bit more than the women.
Usually this cancer develops between 20 and 50 years after exposure to asbestos, and in some cases, the patients swallowed the fibers of the asbestos in rather than inhale them, and they are housed in areas from the stomach to the lymphatic system of the human body. It does not matter the way in which the fibers have entered the body, they may end up staying in delicate fabrics and then get to other places of the body.
In the case of the cancer peritoneal mesothelioma, these fabrics can be coated on the inner side of the abdominal cavity or part of the abdominal organs.
