where is the peritoneum in the body
Peritoneal cancer is a rare cancer. It develops in a thin layer of tissue that lines the abdomen. It also covers the uterus, bladder, and rectum. Made of epithelial cells, this structure is called the peritoneum. It produces a fluid that helps organs move smoothly inside the abdomen. Peritoneal cancer is not the same as intestinal or stomach cancer. Nor is it to be confused with cancers that spread (metastasize) to the peritoneum.
