Study: Contraceptive use reduces risk of ovarian cancer

wls
By ABC7
The study finds among women who used oral contraceptives for more than one year the protective effect lasted 2 to 3 decades after stopping.

Protection was not significant in women who used oral contraceptives only for a short period of time, or less than 1 year during their teen years.

Researchers are still trying to determine the mechanism for the protective influence.
