Vitamin A reduces aggressive prostate cancer

High levels of vitamin A (retinol) reduces the risk of aggressive prostate cancer, however eating a diet high in vitamin A may not be enough to reduce the odds of a man getting the disease, according to a study in the April issue of Cancer Epidemiology Biomarkers & Prevention.

The study examined the serum concentrations of retinol in 692 prostate cancer patients and 844 patients without prostate cancer. Men with the highest concentrations of vitamin A had a slightly lower risk of prostate cancer overall, but had a 42 percent reduction in aggressive prostate cancer risk.
