Using contemporary birth control pills, patches or rings which contain both estrogen and progestin has been linked to a reduced risk for ovarian cancer in women of reproductive eggs.
The study even backed prior data that showed similar results with the use of older forms of oral birth control that were followed until the 1980s.
The authors said, ”Based on our results, contemporary combined hormonal contraceptives are still associated with a reduced risk of ovarian cancer in women of reproductive age, with patterns similar to those seen with older combined oral products.”
The researcher’s analyzed data of women aged between 15 to 79 from 1995 to 2014. The study rejected women who had been under treatment for infertility, cancer or blood clots and the study concentrated on women of reproductive age, between 15 and 49.
Based on their study, researchers believed that hormonal birth control prevented estimated 21% of ovarian cancers in women.
The full study was published in the journal BMJ.
