Vitamin intake and breast cancer risk

A new study suggests that vitamins B6 and B12 may reduce the risk of breast cancer, particularly in postmenopausal women.

"BACKGROUND: High intake of folate, vitamin B(6), and vitamin B(12) have been hypothesized to lower the risk for breast cancer. "

"CONCLUSIONS: In this population, high intakes of folate and vitamin B(12) were independently associated with decreased breast cancer risk, particularly among postmenopausal women."
