Breast Cancer Risk is Increased by All Hormonal Contraceptives



According to a study that was published on Tuesday, all hormonal contraceptives, including the increasingly popular progestogen-only pills, carry a slightly increased risk of breast cancer.

The study’s researchers emphasized that the benefits of hormonal contraceptives, including their protection against other forms of female cancer, must be balanced against the increased risk of breast cancer.

Two-hormone contraceptives, or combined contraceptives, that use both estrogen and progestogen, have been linked to an increased risk of breast cancer in previous studies.

Although progestogen-only contraceptives have been in use for well over a decade, little research had been done on their connection to breast cancer before.

The study, which was published in the journal PLOS Medicine, found that hormonal contraceptives that used both estrogen and progestogen had about the same risk of causing breast cancer as those that only used progestogen.

The study found that women who use hormonal contraceptives are 20-30% more likely than those who do not to develop breast cancer.

The results are similar to those that have been published in the past, including in a large 1996 study.

Whether it is an oral pill, intrauterine device (IUD), implant, or injection, or a combination pill or a progestogen on its own, the risk is about the same.

The study’s authors calculated the absolute excess risk of hormonal contraceptives taking into account the age-related rise in breast cancer risk.

They stated that there were eight cases of breast cancer per 100,000 for women between the ages of 16 and 20 who used hormonal contraceptives for five years.

There were 265 cases per 100,000 people between the ages of 35 and 39.

The concentrate additionally affirmed, similar to other people, that the risk of breast cancer decreases in the years after a woman quits utilizing hormonal contraceptives.

The findings were described as “reassuring in that the effect is modest” by Stephen Duffy, a professor at the Queen Mary University of London who did not participate in the study.

Nearly 10,000 women under 50 who developed breast cancer between 1996 and 2017 in the United Kingdom, where progestogen-only contraception is now as common as combined contraception, were included in the study.

According to Reeves, there are a number of reasons why progestogen-only contraceptives are becoming more popular.

Women who are breast-feeding, who may be at risk for cardiovascular issues, and smokers over the age of 35 are all encouraged to take them.
