How to Use This Calculator
  1. Enter your age and total PSA level (ng/mL) from your most recent blood test.
  2. Input prostate volume (cc) from ultrasound if available, for PSA density calculation.
  3. Enter a prior PSA value (ng/mL) and months since that test to calculate PSA velocity.
  4. Add your free PSA percentage (%) if available — lower values increase cancer suspicion.
  5. Review Overall risk score (0–100), Estimated cancer probability (%), and Velocity concerning flag to share with your doctor.
