The prostate is a gland located below the bladder and wrapped around the urethra, normally the size of a chestnut, and is 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 elderly people over 60 years old. Because of the hidden location of the prostate gland, the cancerous area mostly occurs in the posterior peripheral lobe of the gland, and the early stage of the cancer does not press on the urethra and cause difficulty in urination, so there are often no symptoms in the early and middle stages of the disease, and it is difficult to alert the patients; even if there is some discomfort, such as difficulty in urination, it is often mistaken as a manifestation of old age or due to prostate hypertrophy, which delays the early diagnosis and treatment. When the tumor enlarges to a certain extent and exerts pressure on the urethra, it is often not early. There are even many patients who first develop 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 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 patient’s quality of life. 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 efficacy after anti-androgen treatment and can be combined with local radiotherapy or chemotherapy according to the situation.
