Understanding PSA Testing

<p>The PSA test measures a protein made by the prostate in your blood. It is the most common tool for prostate cancer screening and for monitoring men who have already been diagnosed.</p><h2>What the Number Means</h2><p>A PSA below 4 ng/mL is usually considered normal, but there is no single cutoff that fits everyone. Levels between 4 and 10 are a gray area, and values above 10 raise more concern. Your age and prostate size also matter.</p><h2>What Raises PSA Besides Cancer</h2><p>BPH, prostatitis, recent ejaculation, a digital rectal exam, and even a long bike ride can temporarily raise PSA. This is why one elevated result does not mean cancer.</p><h2>Trends Matter More Than One Number</h2><p>Doctors look at how PSA changes over time. A steady rise, called PSA velocity, is more meaningful than a single reading and may prompt further testing.</p>
