Thanks for the info, much appreciated. I will definitely go through the sources provided. Having had prostate cancer five years ago and having 0 PSA results thus far, I need to be cautious.
Re: Selenium, A quote from a study reads "On the basis of multivariable analyses, men who consumed the lowest amount of selenium (1 to 24 μg/day) after being diagnosed with prostate cancer had an 18% higher risk for prostate cancer mortality compared with nonusers (hazard ratio, 1.18).
This risk increased by 33% in men who consumed between 25 and 139 μg of supplemental selenium a day (HR, 1.33) and by 60% among men who consumed 140 μg of supplemental selenium or more per day (HR, 2.60)."
Actually there seems to be some debate though, regarding Vit C and Vit E and prostate cancer. But it seems results are a bit more definitive regarding Selenium.
