Biopsy Calculator for Current Risk

This calculator provides an estimate for how likely a man is to have more aggressive cancer on his next surveillance biopsy. Specifically, this calculator predicts the risk of an increase in Gleason score at the next biopsy for men who undergoing active surveillance. It is not intended to provide a risk estimate for patients who have not yet been diagnosed with prostate cancer. The estimate from this calculator may help decide whether a biopsy is necessary at this time.

Calculator for Future Progression on Active Surveillance

This calculator provides an estimate for how likely a man is to have more aggressive cancer found in a surveillance biopsy during the next 4 years. Specifically, this calculator predicts the risk of an increase in Gleason score within the next 4 years for men who are undergoing active surveillance. This calculator is intended only for patients who have had at least one biopsy after their initial diagnosis. The estimate from this calculator may help decide how long a biopsy may be delayed.
