Studies have shown that tomatoes and other foods containing lycopene may be effective in preventing prostate cancer. Two large-scale prostate cancer prevention trials have shown that finasteride or dutasteride (a drug used to treat benign prostatic hyperplasia) can reduce the incidence of prostate cancer by 25%, but may increase the risk of high-grade prostate cancer.
