Story highlights The link between oral contraceptives and breast cancer is already well-established
A new study found the risk increased with longer use
(CNN) Birth control can increase a woman’s threat of breast tumor by up to 38%, depending on how long she has taken it, a fresh study finds.
The risk was connected with all types of hormonal contraception — such as the pill, injections or IUDs — in comparison to women who’ve never used them.
Researchers from the University of Copenhagen analyzed data from 1.8 million females beneath the age of 50 in Denmark. They used the women for almost 11 years, normally.
The amount of breast cancer risk increased the longer a woman had been taking hormonal contraceptives, with the common risk increase being 20% among all current and recent users of these forms of contraceptives.
The researchers saw a 9% heightened breast cancer risk among women choosing hormonal contraceptives at under a year, increasing to 38% if a lot more than 10 years.
