“Something good about migraines”
Health Tip – Healthy Next Step – Understanding Cancer Series: Estrogen Receptors/SERMs (National Cancer Institute)
A scientist has found something good to say about migraines. Christopher Li at Seattle’s Fred Hutchinson Cancer Research Center:
“Women who reported a history of migraine had about a 30 percent reduction in their risk of breast cancer, compared to women who did not report a history of migraine.’’
Li thinks it’s related to estrogen. The female hormone can raise the risk of some forms of breast cancer. And women who have migraines can have the headaches when estrogen levels fall. So it could be the estrogen, not the headache, behind the reduction.
Li isn’t basing advice on his study; more work needs to be done first. He does encourage women to get regular mammograms and follow other good health practices.
