Folic acid decreases/increases breast cancer risk. So do I take it or not?

Folic acid decreases/increases breast cancer risk. So do I take it or not?

A few years ago I was at a breast cancer conference where researchers were discussing the effect of alcohol. I had sat through a couple of hours of doom and gloom when, right at the end, one of them mentioned that taking a folic acid supplement appeared to reduce the associated risks. So, on the way home, I bought a jar of folic acid tablets and a bottle of wine to celebrate. I’ve been taking the folic acid ever since.

Then, today, I read that high folic acid may increase breast cancer risk.

This article doesn’t mention that these experiments were performed on rats, so it’s very early days. And the author does concede elsewhere that the role of folic acid in the development and progression of breast cancer is highly controversial because some studies have concluded that it may offer protection against breast cancer.

After reading all of that conflicting information I could do with a drink, but should I or shouldn’t I swallow the pill?
