Mesothelioma

Peritoneal mesothelioma is a form of mesothelioma, a cancer of the lining of the abdominal cavity. It is less common than the pleural form of mesothelioma, comprising approximately one-fifth to one-third of the total number of mesothelioma cases diagnosed. According to the SEER (Surveillance, Epidemiology, and End Results) database, these diagnoses are approximately 54.7 per cent male versus 45.3 per cent female, with the median age being 65-69.

One of the most common types of mesothelioma is malignant pleural mesothelioma, which often originates within the chest cavity and can, at times, involve the lungs as well. This form of mesothelioma can spread to numerous organs in the body, even the brain, and tends to do so more frequently.
