A new study shows women who have a history of migraines have a reduced risk of getting breast cancer.Scientists at the Fred Hutchinson Cancer Research Center in Seattle studied more than 9,000 women, half of whom had breast cancer, the other half were healthy. They were looking for a possible relationship between migraines and breast cancer since both are related to hormones.

Migraines can be triggered by a drop in estrogen, while increased estrogen levels are known to boost breast cancer risk.

Their findings were reported in Cancer Epidemiology Biomarkers and Prevention.
