Stage IC: The cancer is in 1 or both ovaries or fallopian tubes, with any of the following:
- Stage IC1: The tumor ruptures while it is being removed surgically, called intraoperative surgical spill.
- Stage IC2: The tumor wall is ruptured before surgery, or there is cancer on the surface of the ovary or fallopian tube.
- Stage IC3: Cancer cells are found in fluid buildup in the abdominal cavity, called ascites, or in the samples of fluid from the peritoneal cavity taken during surgery.
The cancer involves 1 or both of the ovaries or fallopian tubes and has spread below the pelvis, or it is peritoneal cancer.
