Treatment Methods: Combination of surgery, chemotherapy, and radiation therapy. Palliative treatments may also be used to relieve symptoms.

Definition: Peritoneal mesothelioma originates in the lining of the abdomen and is the second most common type after pleural mesothelioma, attributed mainly to asbestos exposure.
