Higher folate (B vitamin) levels may keep prostate cancer from recurring

The body needs folate to make and repair DNA, and low folate levels may contribute to cancer, but results from earlier prostate cancer studies have been mixed.

Doctors in this study wanted to find a link between circulating levels of folate and cancer recurring by following 135 men with prostate cancer who had their prostate gland removed.

Doctors measure prostate specific antigen (PSA) levels to help determine if cancer may be recurring, since stray prostate cells can later metastasize in lymph or bone. Compared to men with lower levels, men with higher folate levels before surgery were 58 percent less likely to have signs of cancer recur.
