Diet and lifestyle
The data on the relationship between diet and prostate cancer is poor. There is little if any evidence to support an association between trans fat, saturated fat and carbohydrate intake and risk of prostate cancer. Evidence regarding the role of omega-3 fatty acids in preventing prostate cancer does not suggest that they reduce the risk of prostate cancer, although research work in going on for more in details. Vitamin supplements appear to have no effect and some may increase the risk. High calcium intake has been linked to advanced prostate Cancer. Consuming fish may lower prostate cancer deaths but does not appear to affect its occurrence. Some evidence supports lower rates of prostate cancer with a vegetarian diet. There is some tentative evidence for foods containing lycopene and selenium. Diets rich in cruciferous vegetables, soybeans and other legumes may be associated with a lower risk of prostate cancer, especially more advanced cancers. Men who do regular work out, may have a slightly lower risk, especially vigorous activity and the risk of advanced prostate cancer.
In those who are being regularly screened 5-alpha-reductase inhibitor (Finasteride and Dutasteride) reduce the overall risk of being diagnosed with Prostate Cancer. However, there is insufficient data to determine if they have an effect on the risk of death and may increase the chance of more serious cases.
