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.
The most important thing is that you have to be able to get a good idea of what you are doing.
After all this talk, what exactly is the situation of prostate cancer?
Prostate cancer is the most common malignant tumor of the male reproductive system, 95% of which are adenocarcinoma. The age of onset is at a low level before 55 years old, and gradually rises after 55 years old. The incidence increases with age, with the peak age being 70-80 years old! After reading these figures, some of you are starting to worry.
So how exactly is prostate cancer staged?
In order to guide treatment and judge prognosis, prostate cancer is clinically classified into low, intermediate and high risk based on serum PSA, Gleason score and clinical stage.
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)
Etiology of prostate cancer
1.Age factor
According to the research, the incidence of prostate cancer is highest in blacks, followed by whites and finally Asians.
