Ovarian cancer stages

Making an educated treatment decision begins with knowing the stage, or progression, of the disease. Using the results from your diagnostic tests, our cancer experts will develop a treatment plan tailored to you, based on the stage of your cancer and other factors. In most cases, ovarian cancer is staged during your initial surgery.

If you have been recently diagnosed, we will review your pathology to confirm you have received the correct diagnosis and staging information, and develop a personalized treatment plan for you. If you have a recurrence, we will perform comprehensive testing and identify a treatment approach tailored to your needs.

Stage I ovarian cancer

In stage 1 ovarian cancer, the cancer is confined to the ovaries and hasn’t spread to the abdomen, pelvis or lymph nodes, or to distant sites. Stage I has three subcategories:

  • IA: The cancer is limited to one ovary, and the tumor is confined to the inside of the ovary.
  • IB: The cancer is inside both ovaries but is confined to the inside of the ovaries.
  • IC: The cancer is in one or both ovaries, and one of these statements is true:
    • Cancer cells leaked into the abdomen and pelvis during surgery. (IC1)
    • Cancer is on the outside of at least one ovary or the tissue surrounding the tumor ruptured before surgery. (IC2)
    • Cancer cells were found in the abdominal fluid. (IC3)
