Prostate cancer is a kind of high incidence malignant tumor in Europe and America. It is a constant threat to the health of men. It is currently believed that its occurrence is related to genetic factors, in addition to sexual activity, dietary habits, and age. Those who are more sexually active have an increased risk of developing prostate cancer. Older men over 55 years of age need frequent medical checkups. Before liberation, the incidence of prostate cancer in China was extremely low. In recent years, as people’s living standards improve and the proportion of meat in the composition of their diet increases, the incidence of prostate cancer increases year by year, especially in economically developed cities or provinces. Because prostate cancer is often asymptomatic in its early stages. Usually when symptoms appear, they are in advanced stage. If you have difficulty in urination, thin urine line or pain in the back, you need to check your prostate. Prostate cancer is often prone to bone metastasis, causing bone pain or pathological fracture or paraplegia. This is why early detection of prostate cancer is so important. The diagnosis of prostate cancer mainly relies on rectal examination, serum PSA, pelvic MRI examination, CT is not as good as MRI for diagnosing early prostate cancer diagnosis. if your own physical examination results in serum PSA higher than 10ng/ml, or long-term difficulty in urination and oral medication is not effective, you need to go to the hospital urology department. For older men, how should we prevent the occurrence of prostate cancer? A number of German professors have found through long-term research that the best way to prevent and control prostate disease is now – “proper diet”. The incidence of prostate disease is related to men’s androgen, fat and cholesterol intake and lifestyle, with the most critical factor being dietary habits. The incidence of prostate cancer in China is 1/25th of that in Germany, but the advantage is gradually lost when Chinese immigrate to Germany. The Chinese habit of drinking green tea also plays a role in the prevention and treatment of prostate disease. As the amount and duration of tea drinking increases, the more obvious the effect of green tea becomes. The most important thing is to have a good understanding of the way you are doing things. The isoflavones in soy reduce the damaging effects of androgens and inhibit and kill cancer cells. You should eat more of various vegetables. In addition to cabbage, there are vegetables such as cauliflower and broccoli that are also effective in preventing prostate cancer. In addition, you can also eat some flax seeds and tomatoes every day. Tomatoes contain lycopene, which has a preventive and curative effect on prostate cancer.
