ALERT: Birth Control STILL Linked To Cancer

Women who are using birth control have something else serious to worry about besides possibly giving birth: cancer. Birth control can increase a woman’s risk of breast cancer by up to 38%, depending on how long she has taken it, a new study finds.

The risk was associated with all forms of hormonal contraception — such as the pill, injections or IUDs — when compared with women who have never used them.

Many women have believed that newer hormonal contraceptives are much safer than those taken by their mothers or grandmothers, which had higher doses of estrogen, but this study proves otherwise.

Researchers from the University of Copenhagen analyzed data from those nearly two million women (1.8 million to be exact) under the age of 50 and followed the women for nearly 11 years, on average.

The level of breast cancer risk increased the longer a woman had been taking hormonal contraceptives, with the average risk increase being 20% among all current and recent users of these forms of contraceptives.

The researchers saw a 9% increased breast cancer risk among women taking hormonal contraceptives for under a year, rising to 38% if more than 10 years.

Among women who had been using hormonal contraceptives for more than five years, a slight risk persisted for at least five years after they stopped, according to the study published Wednesday in the New England Journal of Medicine.
The results suggested a “rapid disappearance of excess risk of breast cancer after discontinuation of use among women who have used hormonal contraceptives for short periods,” the authors write in the paper. The authors noted that other studies have found no evidence of a persistent risk.

“These results do not suggest that any particular preparation is free of risk,” David Hunter, professor of epidemiology and medicine at the Nuffield Department of Population Health in the UK said to CNN.

However, Hunter also stresses that “breast cancer remains a relatively rare disease in younger women.” In women under 35 included in the study, taking hormonal contraceptives for less than one year resulted in 1 extra case per 50,000 women, he said.

“The number of cases increases with age because the risk of breast cancer increased with age,” said Hunter.
