The Prostate-Specific Antigen (PSA) test is a blood test commonly used for screening prostate cancer. This test measures the level of prostate-specific antigen, a protein produced by both cancerous and noncancerous cells in the prostate—a small gland located below the bladder in men. While a small amount of PSA is typically present in the bloodstream, elevated levels can indicate the presence of prostate cancer
