Background: Many epidemiological studies have investigated the association between
folate intake, circulating folate level and risk of breast cancer; however, the findings were …

Background Previous observational studies regarding the existence of an association
between folate intake and the risk of breast cancer have been inconsistent. This study aimed …

Background Epidemiologic findings are inconsistent concerning risk for breast cancer
associated with low folate intake or blood folate levels. We performed a meta-analysis of …

Although not uniformly consistent, epidemiologic studies generally suggest an inverse
association between dietary intake and blood measurements of folate and breast cancer …

Background: There is limited evidence on the association between dietary folate intake and
the risk of breast cancer (BC) by hormone receptor expression in the tumors. We …

Folate is involved in DNA synthesis, repair, and methylation. It has been hypothesized that
high intake of folate may reduce the risk of human cancers, including cancer of the breast …

Background: Epidemiologic studies of the association of folate intake with breast cancer risk
have been inconclusive, and few have investigated how related nutrients modify this …

Folate plays an important role in DNA methylation, and aberrant methylation of the estrogen
receptor (ER) gene may be related to the loss of ER gene expression in breast tumors. Thus …

Background: Folate is a B vitamin involved in one-carbon metabolism and has been
postulated to influence the risk of breast cancer. However, epidemiologic studies of folate …

Folate is involved in the synthesis of nucleotides and amino acid metabolism such as
methylation of homocysteine to methionine. Methionine is activated by adenosine …
