Stages of Ovarian Cancer

According to the Mayo Clinic, ovarian cancer is staged from I through IV, which indicates earliest to most advanced. Staging is determined at the time of surgical evaluation of the disease:

  • Stage I. Ovarian cancer is confined to one or both of the ovaries.
  • Stage II. Ovarian cancer has spread to other locations in the pelvis such as the uterus or fallopian tubes.
  • Stage III. Ovarian cancer has spread to the lining of the abdomen (peritoneum) or to the lymph nodes within the abdomen. This is the most common stage of disease identified at the time of diagnosis.
  • Stage IV. Ovarian cancer has spread to organs beyond the abdomen.
