Birth Control Pill Linked to Brain Tumors

Posted on 22 January 2015 by admin

Dr. David Gaist, a neurologist at Odense University Hospital and the University of Southern Denmark, and his colleagues found that women taking hormonal contraceptives — those containing estrogen, progestin or a combination of both — showed higher rates of a rare brain tumor known as glioma. Their results, published Thursday in the British Journal of Clinical Pharmacology, raise questions about the connection between oral contraceptives and brain cancer, but shouldn’t yet be interpreted as a reason to stop taking birth control, says Gaist.

Using data from Denmark’s national registries of health records, cancer cases and prescriptions, Gaist zeroed in on the women aged 15 years to 49 years diagnosed with glioma, and then analyzed whether they were prescribed contraceptives and for how long. Overall, women who had used hormonal contraceptives at any point in their lives showed a 50% higher risk of developing the brain tumors compared to those who had not used them. And women who used the birth control for more than five years nearly doubled their risk of the cancer. Still, Gaist says, since gliomas are rare, even a doubling of a rare event is still a small risk.
