stage I ovarian epithelial and fallopian tube cancer  listen  (...oh-VAYR-ee-un EH-pih-THEE-lee-ul ... fuh-LOH-pee-in ... KAN-ser)

  Cancer is found in one or both ovaries or fallopian tubes. Stage I is divided into stages IA, IB, and IC. In stage IA, cancer is found inside a single ovary or fallopian tube. In stage IB, cancer is found inside both ovaries or fallopian tubes. In stage IC, cancer is found inside one or both ovaries or fallopian tubes and one of the following is true: (1) cancer is also found on the outside surface of one or both ovaries or fallopian tubes; or (2) the capsule (outer covering) of the ovary has ruptured (broken open); or (3) cancer cells are found in the fluid of the peritoneal cavity (the body cavity that contains most of the organs in the abdomen) or in washings of the peritoneum (tissue lining the peritoneal cavity).

Three-panel drawing of stage IA, IB, and IC ovarian cancer; first panel shows a stage IA tumor inside one ovary. The second panel shows two stage IB tumors, one inside each ovary. The third panel shows two stage IC tumors, one inside each ovary, and one tumor has a ruptured capsule. An inset shows cancer cells floating in the peritoneal fluid surrounding abdominal organs. Also shown are the fallopian tubes, uterus, cervix, and vagina.
