Ovarian Cancer

Survivability of Ovarian Cancer

The survivability of ovarian cancer can in some cases depend on the woman’s age. Women under the age of 65, for instance, are more than twice as likely to survive for five years after an ovarian cancer diagnosis (57 percent) than women 65 and older (27 percent).

Below are the relative five-year survival rates (meaning, the likelihood a woman to survive after a diagnosis for five years compared to women the same age who don’t have cancer) for invasive epithelial ovarian cancer and ovarian tumors that have low malignancy, according to the American Cancer Society.

Invasive epithelial ovarian cancer

  • Stage I: 89 percent
  • Stage IA: 94 percent
  • Stage IB: 91 percent
  • Stage IC: 80 percent
  • Stage II: 66 percent
  • Stage IIA: 76 percent
  • Stage IIB: 67 percent
  • Stage IIC: 57 percent
  • Stage III: 34 percent
  • Stage IIIA: 45 percent
  • Stage IIIB: 39 percent
  • Stage IIIC: 35 percent
  • Stage IV: 18 percent

Low-malignancy ovarian tumors

  • Stage I: 99 percent
  • Stage II: 98 percent
  • Stage III: 96 percent
  • Stage IV: 77 percent
