To understand prostate cancer, you have to start by understanding the prostate! The prostate is a gonadal organ that is unique to men. The prostate is located in a special place, in front of the pubic symphysis and behind the rectum. It has a bladder on top and a penis on the bottom, with the urethra running through the middle of the gland and choking the top of the urethra. Therefore, when there is an abnormality in the prostate, it often affects urination. The prostate is generally divided into 5 pages: the front page, middle page, back page and both pages. after the age of 40, the middle page can become enlarged and bulge upwards into the bladder, making the bladder bulge significantly and pressing on the urethra causing difficulty in urination.

Low-risk prostate cancer (PSA<10ng/ml, Gleason score<=6, clinical stage<=T2a) Intermediate-risk prostate cancer (10ng/ml<=PSA<=20ng/ml, Gleason score=7, clinical stage=T2b) High-risk prostate cancer (PSA>20ng/ml, Gleason score>=8, clinical stage>=T2c) According to the research, the incidence of prostate cancer is the highest among blacks, followed by whites and finally Asians.
