Vitamin E and the Risk of Prostate Cancer: Klien et al (2011) conducted thefollowing study to determine the effect of vitamin E and selenium treatment onthe risk of developing prostate cancer in healthy men.

To be eligible to participate, the men had to take a rectalexamination that showed he was not suspicious of having prostate cancer andbe aged 50 years or older for black men and 55 years or older for all others.Each man was randomly assigned to receive one of four treatments: selenium,vitamin E, selenium and vitamin E together, or a placebo. The men werefollowed up after 8 years to see if they had developed prostate cancer or not.The main question of interest is to determine if the risk of developing prostatecancer differs by the treatment taken.
