New Study Reveals Misconceptions About Birth Control and Breast Cancer Risk
A massive study published in the Journal of the American Medical Association (JAMA) Oncology has found that hormonal birth control remains safe overall, but it also identified small differences in breast cancer risk based on the hormones used in the formulation. The research, which tracked over 2 million teenage girls and women under age 50 for more than a decade, revealed that current or recent users of hormonal contraceptives had a slightly higher risk of developing breast cancer.
However, the study's findings have been distorted on social media, with many online warnings claiming that birth control causes cancer and is as dangerous as smoking. This misinformation is not only alarming but also misleading, as the study found that the increased risk is relatively small and short-term, with most cases disappearing within five to 10 years after stopping.
The researchers observed a small increase in breast cancer diagnoses among current or recent users of hormonal contraceptives, with women who had used birth control having about a 24% higher rate of breast cancer than those who hadn't. However, this translates to only 13 extra cases per 100,000 women per year β equivalent to one extra case every seven and a half thousand users.
The study's lead authors emphasized that the findings should be viewed with caution, as they counted both invasive breast cancers and early, noninvasive lesions that may never become life-threatening. Experts warn that studies like this can easily be taken out of context online and reduced to a single alarming number, leading to unnecessary alarm and misinformation.
Physicians emphasize that for most patients, the study reinforces what they already discuss in the exam room: that hormonal birth control is broadly safe, and decisions should be tailored to each woman's needs and values. Doctors say that the study's results won't change how they advise their patients and that women should not stop using their birth control.
The study highlights the importance of nuance when discussing women's health on social media, where misinformation can spread quickly without context. Reproductive health advocates urge caution and emphasize the need for accurate information on sexual health and contraceptive methods.
While hormonal birth control has its risks, it also provides numerous health benefits beyond pregnancy prevention, including reducing heavy periods, easing pain from endometriosis, and lowering the risk of ovarian and uterine cancers for years after stopping. As one expert noted, "even small risks are worth discussing but should be weighed against the risk of an unintended pregnancy."
