On call: Selenium and vitamin E for prostate cancer
Selenium and vitamin E for prostate cancer
Q. I have been taking selenium in the hope that it would prevent me from getting prostate cancer. But I heard on the radio that the National Cancer Institute is advising men to stop taking selenium. Should I stop it?
A. Many of us shared the hope that selenium might reduce the risk of prostate cancer. The optimism stemmed from a 1996 report from the Nutritional Prevention of Cancer Trial, which found that 200 micrograms (mcg) of selenium a day reduced the risk of prostate cancer by a startling 63%. A series of observational studies followed; although the results were mixed, many suggested that selenium might help.
