Purpose We examined the association of plasma B-vitamins and metabolites, and related
genetic variants, with risk of breast cancer among predominantly premenopausal women …

Epidemiological studies have reported inconsistent findings for the association between B
vitamins and breast cancer (BC) risk. We investigated the relationship between biomarkers …

Prior epidemiologic findings for plasma folate and B‐vitamins and breast cancer risk are
inconsistent and have not assessed the influence of folic acid fortification. Therefore, we …

Background: B vitamins such as folate, vitamin B-6, and vitamin B-12 are coenzymes that
are important for DNA integrity and stability. Deficiency in these B vitamins may promote …

Epidemiologic studies focusing on the association between 1-carbon metabolism-related
vitamins (ie, folate, vitamin B 6, vitamin B 2, vitamin B 12) and breast cancer risk have …

Background: Few epidemiologic studies have examined very high intakes of folate and
whether consumption of nutrients involved in one-carbon metabolism is associated with …

Background Low dietary folate intake is associated with several neoplasias, but reports are
inconsistent for breast cancer. Additionally, the association of folate with breast cancer …

Background: High intake of folate, vitamin B6, and vitamin B12 have been hypothesized to
lower the risk for breast cancer. We conducted a population-based case-control study to …

Background: B vitamins [vitamins B-6, B-9 (folate), and B-12] play important roles in
nucleotide biosynthesis and biological methylation reactions, aberrancies of which have all …

Breast cancer is the second leading cause of cancer mortality among women. Given its
important role in DNA methylation and synthesis, one-carbon metabolism may affect breast …
