WASHINGTON (Reuters) - Men who take too much zinc may be raising their prostate cancer (news - web sites) risk, U.S. researchers said on Tuesday.
Compared with nonusers, men who took more than 100 mg a day of zinc supplements had more than twice the risk of advanced prostate cancer, the team at the U.S. National Cancer Institute (news - web sites) found.
These levels are far above the recommended 11 mg of zinc a day. However, in the United States, 10 percent of men who take zinc supplements take 2 to 3 times more than this.
Zinc supplements are popular for, among other things, their alleged benefit in preventing or reducing the severity of colds.
Zinc builds up in the prostate, the gland involved in semen production. Prostate cancer is the second most common cancer among U.S. men after skin cancer. It kills nearly 30,000 men a year.
Dr. Michael Leitzmann of the National Cancer Institute and colleagues looked at surveys filled out by 46,974 men taking part in a broad-reaching and ongoing study of health professionals.
Writing in the Journal of the National Cancer Institute, they said they found men who took more than 100 mg a day of zinc doubled their risk of advanced prostate cancer, as did men who took the supplements for 10 years or more.
