Prostate-Specific Antigen (PSA) is a protein produced by cells of the prostate gland in men. The PSA test measures the level of this protein in the blood and is commonly used as a screening tool for prostate cancer. Elevated levels of PSA can indicate prostate cancer, but they can also be caused by non-cancerous conditions like benign prostatic hyperplasia (BPH) or prostatitis (inflammation of the prostate). The test is often used alongside a digital rectal exam (DRE) to assess prostate health. It’s important to note that PSA levels can vary based on age and individual factors, and elevated levels do not always indicate cancer.
