Prostate cancer has become the leading tumor that endangers men’s health in the United States. The incidence of prostate cancer in Asian countries is at a relatively low level in the world. However, the incidence and mortality rates of prostate cancer in Japan, which began to westernize its lifestyle in the 1950s, have also increased. China is now facing this same situation. Some studies have shown that Chinese and Japanese men living in the United States have a higher risk of developing and dying from prostate cancer than their relatives in their respective countries. So what should be done to prevent prostate cancer in terms of lifestyle? 1. Quit smoking: Because cigarettes are a source of cadmium exposure and smoking increases the level of circulating androgens and significantly increases oxidative damage to cells, it is one of the risk factors for prostate. 2. Avoid high-fat diet, which is a more recognized risk factor for prostate cancer. The right amount of selenium, vitamin E, and isoflavones can help prevent prostate cancer. 4. The lycopene in tomatoes, which has a strong antioxidant effect, has a certain role in preventing the occurrence of prostate cancer. The consumption of green tea is relatively high, while prostate cancer presents a low incidence, it is presumed that green tea may have a role in preventing the occurrence of prostate cancer. 5, Asian people like to eat soy products in may have a greater help in inhibiting the occurrence of prostate cancer. The isoflavones in soy can reduce the damaging effects of androgens and inhibit and kill cancer cells. 6. Exercise more. Exercise improves one’s immune system and may also reduce the risk of developing severe type of prostate cancer. In addition, among the survivors of former facial cancer, those who performed 5 hours of high-intensity exercise (running, playing ball and swimming, etc.) per week had 56% lower mortality rate. 7. Regular sexual activity. Some studies have shown that regular sexual activity may reduce the incidence of prostate cancer.
