Prostate cancer is the second most common cause of death among male tumors in Western countries and the sixth most common cause of death in the world. The incidence of prostate cancer in China has been on a significant rise in recent years, from 1.71/100,000 men in 1993 to 11.0/100,000 in 2008, an increase of nearly 10 times. In developed cities such as Shanghai, the incidence of prostate cancer has jumped to the top of male genitourinary malignancies in Shanghai since 2002 and is close to that of western countries. It can be said that the high incidence of prostate cancer in China, especially in developed cities such as Shanghai and Beijing, has come. The prostate specific antigen (PSA) is the most sensitive screening index for prostate cancer, and it is recommended in Europe and the United States to routinely check PSA in men over 50 years of age with urinary symptoms. The risk of prostate cancer increases greatly in these two cases, and a prostate puncture biopsy should be considered. The best way to treat prostate cancer is to do the following, which can be summarized as three early: 1. Early screening: timely screening is of great significance for the timely detection of prostate cancer; 2. Confirmation of diagnosis: It is better to have prostate puncture biopsy in those departments where prostate puncture biopsy is performed by urologists, which can better improve the confirmation rate of prostate cancer and also better control the complications of prostate puncture and reduce the pain of patients. 3. Early treatment: Find specialized team for treatment and it is necessary to individualize the treatment for each prostate cancer patient.
