The PSA test, or prostate-specific antigen test, measures a protein your prostate gland naturally produces, acting like a messenger in your bloodstream. Think of PSA as a signal that tells us how your prostate is doing – when PSA levels are normal, it suggests your prostate is functioning well, but when they're elevated, it can indicate issues like prostate cancer, an enlarged prostate, or inflammation that deserve attention.
This simple blood test is particularly valuable for men over 50 (or over 45 if you have risk factors like a family history of prostate cancer or are African American) because it can help screen for prostate cancer and catch potential problems early, when treatment options for prostate cancer are most effective. While an elevated PSA doesn't automatically mean cancer – it could signal several different prostate conditions – it gives your doctor important information to diagnose prostate cancer or determine if further evaluation is needed.
By tracking your PSA levels over time, including total PSA and free PSA, you and your healthcare provider can stay ahead of health issues, monitor elevated PSA levels, and make informed decisions about your care. Remember, understanding the level of PSA in your blood is crucial for early detection of prostate cancer, as abnormal PSA levels can be a sign of prostate cancer or other significant prostate conditions.
Essential for men over 50, those with prostate symptoms, family history of prostate cancer, or anyone needing comprehensive prostate health screening and assessment, including a prostate biopsy if necessary.
