THURSDAY, Nov. 6 (HealthDay News) -- Women who experience migraines may actually have a 30 percent lower risk of developing breast cancer, say researchers from the Fred Hutchinson Cancer Research Center in Seattle.
Levels of estrogen may be the key to this association: High levels of estrogen are associated with an increased risk of breast cancer, but women who suffer migraines appear to have low levels of the hormone, which may account for the reduction in breast cancer risk, the researchers explained.
"Women who suffer migraines suffer them either when they have fluctuations in their hormone levels or particularly low levels of hormones," said lead research epidemiologist Dr. Christopher I. Li. - Washington Post
