Screening and early detection of prostate cancer
Screening and early detection of prostate cancer are very important. Most commonly the Prostate Specific Antigen (PSA) Blood test is used in combination with a physical exam. However, other tests are now available for patients in the early detection of prostate caner.
Prostate-specific antigen, or PSA, is a protein produced by cells of the prostate gland. The PSA test measures the level of PSA in a man’s blood. PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer or other prostate disorders.
Helps identify patients at increased risk for aggressive disease, thereby aiding in the selection of men for prostate biopsy.
