ABSTRACT
Prostate cancer is the second leading cause of cancer death in men, following lung cancer. Prostate cancer patients are considered to be at low nutrition risk. They infrequently present with nutritional compromise and their treatment causes minimal nutrition-impact symptoms. Hormonal therapy is used in men with advanced disease and it may also be combined with radiation for high-risk early-stage disease. Evidence linking obesity with overall prostate cancer incidence has not been consistent, and in fact, some studies show it may decrease the risk of less-aggressive tumors. Independent of weight status, physical activity appears to have an inverse association with prostate cancer risk. Studies examining the effect of soy protein or isolated isoflavones on prostate-specific antigen (PSA) levels in prostate cancer patients have shown mixed results. Research findings on the role of meat in the etiology of prostate cancer have been inconsistent. A high percentage of men with prostate cancer use dietary supplements, with multivitamins being the most common.
