New study: Vitamin D reduces breast cancer risk:

"The study led by Blackmore KM and colleagues from Mount Sinai Hospital in Ontario, Canada showed that increased intake of vitamin D through diet and exposure to the sun was associated with a 24 percent reduced risk of estrogen-receptor- (ER) and progesterone-receptor- (PR) defined breast cancer.

The study compared 758 cases of breast cancer and 1135 controls without the disease and found those who had high intake of vitamin D were also found to have a 26 percent reduced risk of ER-/PR- breast cancer and a 21 percent decreased risk of ER+/PR- tumors.

The study published in the Oct 15, 2008 issue of American Journal of Epidemiology"
