Prostate Risk Calculator

The nomogram-based Sunnybrook Prostate Cancer Risk Calculator incorporates all known risk factors and tumour markers for prostate cancer and calculates an individual's risk for prostate cancer.

To use this calculator, you need to know the following factors about yourself, or your patient:

  1. Current age
  2. Ethnic background
  3. Family history of any relatives diagnosed with prostate cancer
  4. The presence of urinary symptoms (measured by the International Prostate Symptom Score index)
  5. Total PSA value
  6. Free:total PSA ratio value
  7. Digital rectal exam (DRE) results of prostate (done by a physician)

Using these parameters, the Sunnybrook Prostate Cancer Risk Calculator has been shown to be more accurate than the conventional method of just using PSA and DRE results alone. It has also been validated from other patient populations and performs better than the U.S.-based prostate cancer risk calculator.
