[Cancer of the prostate: influence of nutritional factors. Vitamins, antioxidants and trace elements].
CANCER OF THE PROSTATE AND VITAMINS: Four vitamins have been studied, vitamins A, E, D and C. the results of these studies have been contradictory. Vitamin A and vitamin E would have a protective effect. ANTIOXIDANTS: Carotenes have an activity similar to that of vitamin A. Beta-carotene was positively associated with risk of cancer of the prostate in one study while two others were unable to demonstrate any relationship. Lycopene, the red color in fruits and vegetables, particularly tomatoes, would contribute to a lower risk of prostate cancer.
Cadmium would increase the risk of cancer while selenium would have a protective effect. However studies concerning selenium carry certain methodological biases.
