Can folic acid deficiency increase my risk for breast cancer?

Some research has linked diets low in folate with increased risk for breast cancer.

However, there's no evidence that folic acid supplements lower cancer risk.

Talk to your doctor for more information about folic acid and your own personal needs for this nutrient.
