Millions of men have a PSA test every year, yet very few understand what the number actually means. For decades, PSA has been used to drive decisions about prostate biopsy, prostate cancer diagnosis, surgery, radiation, and active surveillance. But should a single blood test determine your future?
In this episode, Dr. Stephen Petteruti explains what prostate-specific antigen (PSA) really measures, why it was never intended to be used as a standalone screening test, and how biological variation, laboratory differences, ejaculation, inflammation, benign prostatic enlargement (BPH), prostatitis, and other factors can significantly influence PSA results.
You'll learn why PSA should be viewed as a trend rather than a diagnosis, why repeating the test under consistent conditions often provides more meaningful information than reacting to a single elevated result, and how additional tools such as prostate MRI, PSA density, PHI, 4Kscore, ExoDx, PSE, EPI, and sequential monitoring can help guide more informed decision-making.
If you've been told you need a prostate biopsy, have an elevated PSA, are considering active surveillance, or simply want to better understand your prostate health, this episode will help you ask better questions before making life-changing decisions.
Before you consent to a biopsy, invest 30 minutes in understanding the strengths, limitations, and proper interpretation of the PSA test.
