Although modern birth control pills have a lower dose of estrogen than past versions, they are still linked to breast cancer, a new Danish study suggested.
According to the New York Times, older forms of birth control with high doses of estrogen were known to increase the risk of breast cancer in women.
But the study found that modern hormonal birth control — including oral contraceptive pills and some types of intrauterine devices, or IUD’s — still increased the risk of breast cancer.
The study — which followed 1.8 million Danish women for more than a decade — found that users of hormonal contraceptives had 20 percent increase in their relative risk of breast cancer compared to nonusers.
Lidegaard suggested that doctors take time to discuss the risks presented by different types of contraception with their patients, and suggested women reconsider hormonal contraceptives as they age.
