Oral contraceptive pills protect against ovarian and endometrial cancer


A comprehensive study from Uppsala University, involving more than 250,000 women, shows that oral contraceptive use protects against ovarian and endometrial cancer. The protective effect remains for several decades after discontinuing the use. The study is published in the journal Cancer Research.

Ovarian and endometrial cancer are among the most common gynaecological cancers, with a lifetime risk of just over 2 per cent.

In the current study, the researchers found that women who had used oral contraceptive pills had a much lower risk of developing both ovarian and endometrial cancer. The risk was lower also after discontinuing with oral contraceptives and a decreased risk was still detected up to 30–35 years after discontinuation.
