Weighing the benefits and risks of birth control pills
A recent Danish study linked hormonal birth control to an increased risk of breast cancer, but the same contraceptives have also been shown to protect against certain less common cancers, such as endometrial and ovarian, the New York Times reports.
Why it matters: The study published last week raised alarm with its conclusion that users of hormonal birth control see about a 20% increased risk of developing breast cancer. But "it’s really problematic to look at one outcome in isolation. Hormonal contraception has a complex matrix of benefits and risks, and you need to look at the overall pattern," JoAnn E. Manson, a professor of women’s health at Harvard Medical School, told the Times.
