It’s long been known that hormonal contraception, like any medicine, carries some risks. But doctors and women have hoped that the newer generations of low-dose contraceptive pills, IUDs and implants eliminated the breast cancer risk of earlier, higher-dose formulations.
Now a big study from Denmark suggests the elevated risk of getting breast cancer — while still very small for women in their teens, 20s and 30s – holds true for these low-dose methods, too.
In the research published Wednesday in the New England Journal of Medicine, a team of scientists studied 1.8 million women between the ages of 15 and 49. They were looking to see what happened over a stretch of nearly 11 years among women who used hormonal birth control — usually a combination of estrogen and progestin — versus women who relied on non-hormonal contraceptive methods, such as a condom, diaphragm or copper IUD.
