Folic acid may help postmenopausal women with breast cancer
Folate is the circulating form of folic acid, and plays a role in copying and repairing DNA. In this study, doctors followed 498 postmenopausal women with breast cancer for 6.7 years. Researchers took into account the stage of the disease, age at diagnosis, body mass index, childbirth history, hormone replacement therapy, alcohol, diet, and folic acid supplementation.

Overall, women with the highest total circulating folate levels were 59 percent less likely to have died during the study period compared to women who had the lowest folate concentrations. Also, women who used folic acid supplements had significantly higher circulating levels of folate than women who did not take folic acid.
