Matti Narkia on 10 Dec 09"MedWire News: High levels of selenium in the blood may worsen prostate cancer in some men who already have the disease, results of a US study suggest. In recent years, selenium supplements have been promoted as a means of preventing prostate cancer, largely based on observational studies that found higher prostate cancer incidence and mortality in geographical areas that are naturally low in selenium, compared with in those that are naturally high in the mineral. However, the current research findings suggest that "if you already have prostate cancer, it may be a bad thing to take selenium," said study researcher Dr Philip Kantoff, from the Dana-Farber Cancer Institute in Boston, Massachusetts, USA."
