This study looked at plasma folate, vitamin B6, vitamin B12, homocysteine, and risk of breast cancer. They used 712 breast cancer patients and 712 individually matched control subjects. They used a food questioner to determine dietary intake. In this prospective control study they took blood samples to measure plasma levels. Higher plasma folate levels were associated with lower risk of breast cancer. The risk of breast cancer were strong among women who consumed moderate amounts of alcohol. There was an inverse association between plasma vitamin B6 levels and risk of breast cancer was stronger in postmenopausal women than in premenopausal women. Of those premenopausal women who had high levels of vitamin B12 they were associated with low risk of developing breast cancer. The plasma homocysteine was not associated with risk of breast cancer among premenopausal or postmenopausal.I found it very interesting that postmenapausal women were not as effected by low levels of vitamin B12 in association with risk for developing breast cancer. As the female body goes through changes as it ages hormone levels fluctuate. I wonder if this has something to do with vitamin B12. I do believe that it has a relationship with developing breast cancer.
