SAN ANTONIO -- Taking vitamin E may raise a man’s risk of prostate cancer.

San Antonio researchers involved in the study call the findings “profound.”
New results from a study of more than 35,000 men reveal that taking vitamin E increases the risk of prostate cancer among healthy men by 17%.
Men in the study, including some from San Antonio, were taking vitamin E to see if the powerful antioxidant might decrease the risk of developing prostate cancer.
Now, there’s evidence that it does not help prevent the cancer, but actually increases the risk.
The results are published in today’s Journal of the American Medical Association.
Dr. Ian Thompson of San Antonio’s Cancer Therapy and Research Center said the finding is important.
“Until you actually run studies like the study we ran, until you run those studies you don’t know,” Thompson stated. “And to assume that something can’t hurt you and that it might help may not be the right assumption.”
“I feel like it may have helped that I was involved and that there were enough people involved to get these statistics for knowing that vitamin E may be causing cancer,” added study volunteer Dean Byers.
Researchers call these new findings “substantial” since more than half of men over 60 take vitamin E supplements.
They have some decisions to make about whether they want to continue popping those pills.
