Video Archive Eye On Health CBS News medical correspondent Dr. Jon LaPook examines various health issues and treatments.
The largest trial of its kind - known as "SELECT" - hoped Vitamin E and selenium would prevent prostate cancer. But CBS News has learned patients are being told to stop taking the pills - because they don't seem to work, CBS News medical correspondent Dr. Jon LaPook reports. Researchers will continue to monitor the patients in the trial.
"Taking selenium or Vitamin E at the doses that we used in the SELECT trial for an average of five years did not prevent prostate cancer," said Dr. Eric Klein.
The study of more than 35,000 men in their 50s and older began back in 2001.
Doctors at more than 400 sites gave combinations of Vitamin E, the mineral selenium and a placebo.
The supplements failed to prevent prostate cancer - and there were two worrisome trends.
Patients taking Vitamin E alone had a slightly higher rate of prostate cancer.
Men who took selenium alone were more likely to develop diabetes. The researchers believe the increases may just be due to chance.
"The safety issues are of more minor concern and bear further follow-up," Klein said.
Vitamin E and selenium are antioxidants that exist in relatively small amounts in food. Previous studies suggested that higher doses might help prevent prostate cancer.
That's why urologists like Dr. Aaron Katz had high hopes for the trial.
"I'm disappointed with the study. I'm very concerned about the results of the trial," Katz said. "I would have hoped this would have been the way to prevent cancer in this country."
Over the next week, the 35,000 men in the study will be notified of the results and told to stop the supplements.
Katz spoke to one of the participants Monday.
"He's concerned. You've got to be concerned," Katz said. "You're hearing the results of a national trial that you participated in, and are now finding that perhaps I may have increased my risk of developing the disease."
This is a major disappointment, but it is also progress, LaPook reports. Because it's also important to know what does not prevent cancer.

And to tell people to stop taking nutrients your body REQUIRES and few can get enough of in their diet is just reprehensible, unconscionable behavior. They should be telling them to add all the other ones they''re not getting in order to get their body working again. THAT''s the ONLY way to CURE cancer and all the other major diseases. Of course, that would put most doctors and the drug companies out of business -- so yeah, that''ll never happen. I first read about selenium preventing cancer over 25 years ago and have been taking it since than, (vit E even longer) so if they caused cancer I''d be dead by now. But since I take ALL the required nutrients, my body is working the way it''s supposed to be and I don''t have any of the typical American degenerative or infectious diseases.

Unfortunately an all-vegetarian diet leads to an increased risk of brain shrinkage. Besides, it''s not healthy. Although I should clarify- a vegan diet isn''t healthy. Vegetarian can be.
It really comes down to moderation. Anything can and will kill you, if you use it in large enough amounts.
There you go again, waving the Big Pharma flag !
You defeat your own point by trumpeting Gardasil, whilst you and your friends Merck claim it''s the best thing since sliced bread, the FDA are refusing to sanction it''s use for women between 25 and 47. AND tell us O Learned One, how many deaths of young ladies have occoured, is it now 8 or is it 10, and just how many are suffering dreadful side effects, is it a thousand or two thousand ?
Absolutely pointless arguing with you.
the GOP winning anything ... I think you are crazy.
As far as the healthcare issue, at least for your
children (if you have any), please have a plan "B"
......... a good pediatrician.

==================
Thank you for your concern but we have Jesus.
the Easter Bunny .... and by the way ... when you
imply that the "gop will win" .... what is it exactly that you think the GOP will win? If you are thinking
that they are going to win in this current election
cycle .....

You have a lack of faith. Also the GOP will win this election cycle.

That is really sad .... and if you are not getting medical attention for anyone under 18 years old ... probably illegal.

Don''t buy it - I think he''s trolling to get a response out of people. Either that or his parents are brother and sister.

Why do you say sad? If God intends for us to live, he will allow us to live.
