New study links Birth Control and Breast Cancer risks

  • 0

SARASOTA, FL (WWSB) - Hormonal birth control methods are widely believed to be safer than older methods, but a new study has found a link between birth control and breast cancer risks.

Researchers found that women who took hormonal contraceptives, including pills, patches and implantable devices had, on average, a 20 percent increased risk of breast cancer.

The study published in the New England Journal of Medicine looked at data from nearly 2 million women between the ages of 15 and 49 for more than a decade.

Researchers also found the longer women took the contraceptives, the higher their risk. Those who took hormonal birth control for longer than ten years saw their risk of cancer increase to 38 percent. Compared to only a 9 percent increase for those who took the birth control for less than a year.

Another significant finding from the study showed that the risk was the same whether the contraceptive used was newer or from an older generation of drugs.

According to the study, the risks continued even after the women stopped using birth control.
