Guest guest Posted August 31, 2003 Report Share Posted August 31, 2003 From WebMD Too Much Zinc Linked to Prostate Cancer http://my.webmd.com/content/Article/70/80974.htm Zinc supplement use and risk of prostate cancer.

The high concentration of zinc in the prostate suggests that zinc may play a role in prostate health. We examined the association between supplemental zinc intake and prostate cancer risk among 46 974 U.S. men participating in the Health Professionals Follow-Up Study. During 14 years of follow-up from 1986 through 2000, 2901 new cases of prostate cancer were ascertained, of which 434 cases were diagnosed as advanced cancer. Supplemental zinc intake at doses of up to 100 mg/day was not associated with prostate cancer risk. However, compared with nonusers, men who consumed more than 100 mg/day of supplemental zinc had a relative risk of advanced prostate cancer of 2.29 (95% confidence interval = 1.06 to 4.95; P(trend) =.003), and men who took supplemental zinc for 10 or more years had a relative risk of 2.37 (95% confidence interval = 1.42 to 3.95; P(trend)<.001). Although we cannot rule out residual confounding by supplemental calcium intake or some unmeasured correlate of zinc supplement use, our findings, that chronic zinc oversupply may play a role in prostate carcinogenesis, warrant further investigation. http://tinyurl.com/lrx5 There was an earlier study that showed zinc to help apoptosis on PCa cells. http://www.ascb.org/publicpolicy/pressbooks/pressbook01-18.pdf From the above it appears the above study does not to hold true when real men take zince supplements. That is one reason to continue to update your education and why it is important to not jump to take supplements based on early studies. Seems the jury is till out on zinc. Hope this helps.
