Serum PSA

PSA is an abbreviation of prostate-specific antigen. Blood PSA test is an important indicator for detecting prostate cancer, which is of great significance for the early diagnosis and treatment of prostate cancer. Since most patients with prostate cancer are asymptomatic in early stage or show similar symptoms of benign prostatic hyperplasia, it is often not easy to find. Therefore, regular prostate examinations are very important for the prevention and detection of prostate diseases.
