Selenium/vit E "do not cut prostate cancer risk"

Findings from one of the largest cancer chemoprevention trials ever conducted suggest that selenium and vitamin E taken alone or in combination for an average of five and a half years does not prevent prostate cancer.

A team of researchers, coordinated by the USA's Southwest Oncology Group and led by scientists at the University of Texas MD Anderson Cancer Center and Cleveland Clinic, analyzed data gathered from 5,533 participants.

In the randomized, placebo-controlled and double-blind trial, 4.43% of those on placebo were diagnosed with prostate cancer during the five-year duration of the study, while this was 4.56% both for the group taking selenium or selenium plus vitamin E and 4.93% for participants taking vitamin E alone.
