Prostate cancer (PC) is a common malignant neoplasia in males over 50 years. The serum level of prostate specific antigen (PSA) is a tool in the diagnosis of PC and benign prostatic hyperplasia patients that improves the efficiency obtained with the digital rectal examination. The use of PSA increases the detection rates of organ-confined PC. The PSA must be requested by the primary care physician in male population over 45 years and if the result is above the normal levels, the patient must be send to an urologist.
前列腺癌（PC）是50岁以上男性常见的恶性肿瘤。前列腺特异性抗原（PSA）的血清水平是诊断PC和良性前列腺增生患者的一种工具，它提高了直肠指检的诊断效率。PSA的应用提高了局限于器官的PC的检出率。45岁以上男性人群的初级保健医生必须要求检测PSA，如果结果高于正常水平，患者必须转诊给泌尿科医生。
