The Pill might have a small increase to the risk of breast cancer, especially with long-term use.
Modern birth control pills that are lower in estrogen have fewer side effects than past oral contraceptives. But a large Danish study suggests that, like older pills, they still modestly raise the risk of breast cancer, especially with long-term use.
Researchers found a similar breast cancer risk with the progestin-only intrauterine device, and they couldn’t rule out a risk for other hormonal contraceptives like the patch and the implant.
But the overall increased risk was small, amounting to one extra case of breast cancer among 7,700 women using such contraceptives per year. Experts who reviewed the research say women should balance the news against known benefits of the pill — including lowering the risk of other cancers.
“Hormonal contraception should still be perceived as a safe and effective option for family planning,” said Dr. JoAnn Manson, chief of preventive medicine at Harvard’s Brigham and Women’s Hospital, who was not involved in the research.
