Ovarian, Fallopian Tube, and Peritoneal Cancer

The ovaries are organs responsible for containing eggs and producing the hormones estrogen and progesterone. The fallopian tubes allow the passage of an egg from the ovaries into the uterus. The peritoneum is a lining that covers the organs within the abdominal area, including the ovaries and fallopian tubes in women. Any cancer that occurs within these structures is commonly termed “ovarian cancer,” because it is often difficult to distinguish which of these locations the cancer originated. Several types of specific cancers fall under this broad term; however, epithelial carcinoma makes up around 90% of cases.
