According to Reuters, a recent American study shows that women who have a history of migraine headaches are far less likely to develop breast cancer than other women. Good news for me, huh?!

Although the link is not clear, researchers suspect that hormones maybe playing a big role – higher estrogen means higher breast cancer risk, and women with chronic headaches “may have a chronically lower baseline estrogen.”  

…the reduction in risk was for the most common types of breast cancers — those driven by hormones, such as estrogen-receptor positive breast cancer, which is fueled by estrogen, and progesterone-receptor positive breast cancer, which is fueled by progesterone – compared to women who did not have a history of such headaches - Dr. Christopher Li, Fred Hutchinson Cancer Research Center, Seattle, WA
