Greater levels of selenium, vitamin E and the tomato nutrient lycopene have been shown to reduce prostate cancer in one out of every four Caucasian males -- those who inherit a specific genetic variation that’s particularly sensitive to oxidative stress. Conversely, if carriers of this genetic variant have low levels of these vitamins and minerals, their risk of aggressive prostate increases substantially, as great as 10-fold, over their cohorts who maintain higher levels of these nutrients.These results, published in the March 15 issue of the journal Cancer Research, were based on the analysis of 567 men diagnosed with prostate cancer between 1982 and 1995, and 764 cancer-free men from the Physicians Health Study (PHS).
