Ovarian Cancer Key Facts

  • An estimated 21,010 new cases of ovarian cancer will be diagnosed in the U.S. in 2026, with 12,450 deaths expected to result from the diagnosis.
  • While all women are at risk of ovarian cancer, the overall lifetime risk of developing the disease is 1 in 91.
  • The estimated five-year survival rate for patients whose ovarian cancer is detected early is about 92%. However, only about 20% of patients are diagnosed at the early stage.
  • Ovarian cancer can be difficult to diagnose because initial symptoms are similar to gastrointestinal illness and indigestion. Women who experience symptoms daily for more than a few weeks should seek prompt medical evaluation.
