There are three diagnostic methods for prostate cancer: rectal examination, ultrasound-guided prostate biopsy puncture, and serum prostate-specific antigen;
Patients with prostate cancer are mostly older men, and prostate-specific antigen is of great clinical importance and value in the diagnosis and management of prostate cancer;
Prostate antigen is synthesized and secreted only by the prostate gland and can be found in the serum, also known as serum prostate-specific antigen.
Prostate specific antigen is a protein that can only be found in the prostate gland and can be detected in the blood serum, also known as serum prostate-specific antigen;
The synthesis and secretion of prostate-specific antigen increases when prostate tissue becomes cancerous, and is often used to diagnose prostate cancer with an accuracy of 90% to 97%. The most important thing is that it is not the only way to diagnose prostate cancer, but it is the only way to diagnose prostate cancer, and the only way to diagnose prostate cancer is by ultrasound-guided prostate biopsy. The two diseases are different in terms of diagnosis, treatment and prognosis, and regular medical checkups are needed to identify the two diseases and protect the health of the elderly.
