The peritoneal mesothelioma (abdominal mesothelioma)

The malignant peritoneal mesothelioma is a condition extremely rare. Only 100 to 500 cases are diagnosed in the USA every year, less than 30% of all cases of mesothelioma.

Peritoneal Mesothelioma is a cancer affecting the abdominal lining, or peritoneum (Paira-tin-e-um), which is why sometimes referred to the abdomen mesothelioma. This membrane supports and covers the organs of the abdomen.

The peritoneum is composed of two parts, the visceral and parietal peritoneum. The visceral peritoneum covers the internal organs and most of the outer layer of the intestinal tract. Covering the abdominal cavity is the parietal peritoneum.

In these lining cells secrete a fluid that allows organs to move against each other. For example, as the intestines move food into the body. The cells of the Mesothelium are designed to create fluid, but the causes of cancer to overproduce, creating an accumulation of excess fluid in the abdominal cavity.

Because pleural mesothelioma is more common and often spreads to the peritoneal cavity, it is important to determine if the pleural mesothelioma is the main cancer.
