Abstract
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.
