Study links hormonal IUDs to higher breast cancer risk but overall chance remains low

A new study published in JAMA shows that women using hormonal IUDs have a 40% higher risk of breast cancer compared to those not using hormonal contraceptives. This translates to about 14 additional diagnoses per 10,000 women. Despite the increased risk, experts emphasize that the overall chance of developing breast cancer remains low. Previous research has also linked hormonal birth control to breast cancer, but the new study specifically highlights risks associated with IUDs. Health professionals encourage women to discuss their individual risks and options with their doctors. They note that other contraceptive methods, like copper IUDs, do not carry the same risks.
