Selenium Supplements May Increase Prostate Cancer Risk


"Men using these supplements [selenium and/or Vitamin E] should stop, period." These are the words of Alan Kristal, author of a new study examining why some men are at increased risk of prostate cancer when taking these supplements. Men with high selenium levels at baseline who took selenium supplements increased their risk of high-grade cancer by 91% (P=.007).
