Hormone supplements, already shown to be harmful to women, may pose an "urgent" health risk to men, some researchers are warning.
Doctors who treated two men who developed unusually aggressive and fatal prostate cancer within months of taking the same over-the-counter supplement for stronger muscles and "enhanced sexual performance" say testosterone supplements may promote the growth of prostate cancer and stop anti-cancer drugs from working.
"Given that testosterone supplements are in high demand, there is significant concern that HHDS (herbal/hormonal dietary supplements) other than the one evaluated in the current study may pose an urgent human health risk," University of Texas Southwestern Medical Center researchers report in today's issue of the journal, Clinical Cancer Research.
For legal reasons the researchers won't name the supplement, which was removed from the market, and say they have no direct proof that the product caused the highly suspicious prostate cancers.
But a leading Canadian urologist warns that men who take nutritional supplements advertised as having male hormones are "really playing with fire."
"Many men are on androgen replacement therapy or some kind of male hormone replacement and there's always been a concern this may stimulate the growth of prostate cancer cells," says Dr. Laurence Klotz, chief of the division of urology at Toronto's Sunnybrook Health Science Centre.
"It's a very controversial question and the answer is still not clear."
A separate study, this one the latest to look at the risk of hormone therapy for women, found that taking an estrogen-plus-progesterone combination for as little as three years significantly increases the risk of certain breast cancers...click here to continue reading
