Hi,Welcome to HCM. Stage 4 ovarian cancer is not curable. Ovarian cancer is a dangerous cancer because it is asymptomatic and is often not diagnosed until it is in its advanced stages. Between 2000 and 2010, the rates of diagnosis of ovarian cancer have remained relatively stable, with a decrease of less than 1 percent annually in the number of women diagnosed. The mortality rate and life expectancies have remained stable.For stage IV ovarian cancer, the 5-year survival rate is 17.5%. Take care.
