Prostate cancer is the most common malignant tumor in men in Europe and the United States, but it is a rare disease in China in the past. However, with the aging of the population and changes in diet and living environment, the incidence of prostate cancer in China is increasing year by year, especially in economically developed regions such as Shanghai, the incidence rate has reached 14/100,000, ranking first among male genital tumors of the male urinary system. It is a serious problem for men’s health. According to my personal experience, most of the patients diagnosed with prostate cancer more than ten years ago were diagnosed with prostate enlargement before surgery, and the pathology was only confirmed after surgery. The current situation is very different. There is a wealth of information showing that androgens are strongly associated with the development of prostate cancer; other risk factors include genetics, race, diet, and environmental factors; and there is no complete cure for the disease in the medical community to date. Most prostate cancer patients are diagnosed at an advanced stage, so early diagnosis and prevention are especially important. Early diagnosis of prostate cancer For men over the age of 50, screening for prostate cancer is necessary, especially for men with a family history of prostate cancer who should undergo regular checkups and follow-ups after the age of 40. The purpose of prostate cancer screening is to detect and diagnose prostate cancer at an early stage in order to achieve early treatment and satisfactory results. The main methods of screening are rectal examination of the prostate and the detection of serum prostate-specific antigen (PSA). The combination of the two is easy and effective. Abnormalities in either of the two tests, or an increase in PSA levels carried out during a routine annual examination, are associated with further tests such as prostate magnetic resonance spectroscopy and prostate puncture biopsy. Men over the age of 50 with a PSA higher than 10ng/ml have a greater than 67% chance of developing prostate cancer. A small percentage of prostate cancers have a PSA that is not high, less than 4ng/ml, and should be noted. However, elevated PSA does not necessarily mean prostate cancer, for example, benign prostatic hyperplasia and acute prostatitis can also have elevated PSA, which should be combined with rectal examination and other tests for further diagnosis. Prostate cancer prevention measures 1, selective type II 5α-reductase inhibitors, such as Paulownia. It can inhibit the conversion of testosterone into dihydrotestosterone, an active substance with a large effect on the prostate, so it has the potential to inhibit the pro-growth effect of testosterone on prostate cancer cells, and this effect is still under observation in clinical studies and has to be confirmed. It is still under clinical study, and this effect is yet to be confirmed. Moreover, this drug has certain side effects, and it is difficult to be widely used and recognized. 2. Vitamin E can interfere with the ability of prostate cancer cells to produce. When prostate cancer cells are exposed to vitamin E, the level of specific prostate antigen decreases by 90%, showing that the growth of cancer cells is inhibited. In addition, the number of cancer cells was reduced by 25 percent 50 percent. This study supports past research finding that men who take vitamin E supplements have a one-third reduction in the incidence of prostate cancer. Additional foods rich in vitamin E can be consumed mainly almonds, hazelnuts, peanuts, olive oil, spinach and other green leafy vegetables. Those who pay attention to dietary supplements should have no difficulty. 3, avoid risk factors This is difficult to do. Genetics, age, etc. cannot be avoided, but potential environmental risk factors such as high-fat diet, cadmium, herbicides and other unidentified factors may be avoided. 4. Many dietary factors can increase the incidence of prostate cancer. A high-fat diet can promote the development of prostate cancer, and a large intake of dairy products can increase the risk of prostate cancer, while fruits, vegetables and a low-fat diet can reduce the risk of prostate cancer. For example: soybeans, tomatoes, pomegranates, green tea, grapes, strawberries, blueberries, peas, watermelon, garlic, citrus, etc. I especially emphasize the role of tomatoes is more prominent. 5. It is now known that about 60% of the factors that cause prostate cancer come from the living environment. The occupations with significant risk are soap making, perfumes, herbicides, fertilizers and leather industry. In addition, people who are exposed to chemicals, herbicides and fertilizers are at increased risk of prostate cancer. This is why it is especially important to have good protection against occupational diseases. The last thing I need to emphasize is the intensity of sexual life, normal couple life 2 to 3 times a week should be normal, but too often, too chaotic, inevitably the prostate gland repeatedly congested, stimulating the prostate tissue cells to mutate is also one of the causes of prostate cancer.
