When it comes to prostate cancer, people often think that it is the “patent” of Europe and the United States, because in Europe and the United States, the incidence of the disease is as high as 100/100,000 or more, ranking second in cancer deaths. The incidence rate in China is very low, 2 to 3/100,000 10 years ago, but in recent years the incidence rate has gradually increased, and has increased by about four times compared to 10 years ago. It is not easy to detect early the prostate is a gland located below the bladder, wrapped around the urethra, normal as the size of a chestnut, unique to men. According to statistics, there are about 80,000 new cases of prostate cancer in China every year, mainly occurring in middle-aged and older people over 60 years old. Because of the hidden location of the prostate gland, the cancerous area mostly occurs in the posterior lobe of the peripheral zone, and the early stage does not cause difficulty in urination due to compression of the urethra, so there are often no symptoms in the early and middle stages of the disease, which makes it difficult to alert the patients. When the tumor enlarges to a certain extent and exerts pressure on the urethra, it is often not early. In our hospital, many patients first present with bone pain and discover distant bone metastases, only to find out that the primary lesion is from prostate cancer after examination. Prostate cancer is not terrible, early detection and timely treatment can be cured without affecting life expectancy. This shows that early diagnosis of prostate cancer is very important. Men aged over 50 should have a specialist examination once a year, including rectal examination, prostate specific antigen (PSA) and transrectal ultrasonography, and for those who are suspicious, a prostate puncture biopsy. Early prostate cancer treatment has a good prognosis For early prostate cancer, the best treatment is to do radical surgery, that is, when the cancer is confined to the prostate, it will be radically removed, which can achieve a lifelong cure and does not affect the quality of life of the patient. For prostate cancer that penetrates the prostate envelope and has local invasion, radical surgery or debulking surgery can be considered on the basis of neoadjuvant therapy and combined with endocrine therapy. With the improvement of surgical level and anatomical techniques, radical surgery that preserves sexual nerves and blood vessels can restore sexual function for most patients after surgery. Most of the advanced prostate cancers have good results after anti-androgen treatment and can be combined with local radiotherapy or chemotherapy according to the situation. In clinical work, we often encounter patients who have undergone transurethral resection of the prostate for prostatic hyperplasia, and after the surgery, when the pathological examination of the resected prostate tissue is performed, prostate cancer is unexpectedly found, called incidental cancer. This type of prostate cancer is mostly focal, with small tumor size, well differentiated cells, slow growth, little chance of metastasis and good prognosis. The reason for this is that the cause of prostate cancer is not clear and there are no effective preventive measures. The latest research results show that the risk of prostate cancer is two to three times higher for people who do not eat fish than for those who eat fish regularly, and that men with the highest serum lycopene levels are 35% less likely to develop prostate cancer than men with the lowest levels. These findings suggest that eating more fish and tomatoes (tomatoes) has a role in preventing and reducing the incidence of prostate cancer.
