Peritoneal Cancer is a rare cancer of the peritoneum, the fluid membrane that lines the walls of the abdominal cavity.

Peritoneal Cancer is also known as Primary Peritoneal Cancer, Peritoneal Serous Carcinoma, and Extraovarian Cancer. Because you can't remove the walls of the abdomen, the cancer can't be removed by surgery.

It is called Extraovarian Cancer (or cancer outside the ovaries) because it is the same fluid that coats the ovaries, and even though it is not ovarian cancer it is treated as such.

Symptoms include pain you might think due to "gas"; if it does not subside, insist on an ultrasound.

This site is not concerned with where in the body cancer occurs, because all cancers, peritoneal or otherwise, have the same origin in ones biological terrain as charted by Professor Vincent of France in the 1920s. He correlated biological terrain with the onset of cancer. A healthy terrain cannot get cancer, while a debased terrain cannot avoid it. Terrain is mainly the result of ones diet.
