Background: Calcium, vitamin D, and dairy products are highly correlated factors, each with
potential roles in breast carcinogenesis. Few prospective studies have examined these …

Background Although it has been hypothesized that large intakes of the antioxidant vitamins
C, E, and A reduce the risk of breast cancer, few prospective data are available. Methods We …

Background: In several epidemiologic investigations, folate intake has appeared to reduce
the elevated risk of breast cancer associated with moderate alcohol consumption. However …

Background: Experimental and epidemiologic studies have yielded conflicting results on the
relation between vitamin C intake and breast cancer risk. Objective: We investigated the …

The folate metabolism pathway contributes to important metabolic processes, such as RNA
and DNA synthesis, DNA repair, and DNA methylation (1). Previous observations have …

The epidemiological literature reports inconsistent associations between consumption or
circulating concentrations of micronutrients and breast cancer risk. We investigated …

Background: Vitamin D, antiproliferative and proapoptotic in breast cancer cell lines, can
reduce the development of mammary tumors in carcinogen-exposed rats. Current evidence …

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 …

Objective: Laboratory data suggest that several different vitamins may inhibit the growth of
mammary cancers, however epidemiologic data on the relationship between vitamin …

Published data on the association between MTHFR C677T polymorphism and breast cancer
risk are inconclusive. To derive a more precise estimation of the relationship, a meta …
