A recent study, conducted by Danish researchers and published in the New England Journal of Medicine last December 7, reveals that women who take hormonal contraception, whether pill, patch, or an iud, have 20% risk to develop breast cancer.

The study was conducted in Denmark over 1.8 million women aged between 15 and 49 years of age and who have never had cancer or had received treatment for infertility.

Among this panel of women, who were followed for about ten years, 11 517 cases of breast cancer occurred.

The risk increases with the time

According to the study, the number of years of taking the contraceptive influence on the probability of developing cancer of the breast. Thus, the risk would increase to 38 % for women who renew their prescription for more than 10 years.

The researchers also point out that the impact of hormonal contraception can last a long time even after you have stopped. Among women who took hormones for more than 5 years, the risk of breast cancer remained high, even five years after the last. Users under the age of 5 years, they seemed to be spared.
