What is primary peritoneal cancer ?
Primary peritoneal cancer is a relatively rare cancer that begins in a layer of tissue inside of the abdomen called the peritoneum. The peritoneum lines the abdomen, covering the uterus, bladder, and rectum. While primary peritoneal cancer often acts similar to ovarian cancer and is typically treated the same way, these types of cancers are distinctly different. Primary peritoneal cancer is more common in women, but can occur in men, too.
