A new study1of more than 23,200 women with ovarian cancer has confirmed that use of combined oral contraceptives (COC) reduces the risk of ovarian cancer. This effect increases with longer duration of use and persists for many years after stopping. The researchers estimate that about 2 cases of ovarian cancer and 1 death from the disease before age 75 years are prevented for every 5,000 women years of use of combined oral contraceptives.
