This is the gold-standard, definitive procedure for accurately diagnosing prostate health. It's performed by your urologist if your PSA is high or an exam is abnormal. This is not one sample; it involves taking multiple (often 12) "cores" from precise, pre-planned zones of the prostate. This "systematic mapping" is critical. It allows our pathologists to create a 3D map of your prostate, determining if cancer is present, where it is, and what its 'Gleason Score' (aggressiveness) is. This precision-guided procedure is the essential, conclusive step you need to get a definitive diagnosis and build a personalized, effective treatment plan.
