Lower Risk of Breast Cancer for Women With Migraine

Finally, some good news for migraineurs. Women with migraine had a 30 percent lower risk of breast cancer than those without, according to a recently released study. Hormonal changes, which commonly trigger migraine, are a potential link.

In particular, migraine history appeared to reduce the risk of the most common subtypes of breast cancer: those that are estrogen-receptor and/or progesterone-receptor positive. Such tumors have estrogen and/or progesterone receptors, or docking sites, on the surface of their cells, which makes them more responsive to hormone-blocking drugs than tumors that lack such receptors.

The biological mechanism behind the association between migraines and breast cancer is not fully known, but Li and colleagues suspect that it has to do with fluctuations in levels of circulating hormones.
