Risk of High-Grade Cancer on Prostate Biopsy

Print

This tool is designed to calculate the likelihood of having high-grade prostate cancer in men who have been considered eligible for prostate biopsy by a urologist. If you have not been examined by a urologist, the results produced by this calculator will be a considerable overestimation of your risk for prostate cancer (that is, it will give a risk that is too high). This tool is not applicable for men who have already been diagnosed with prostate cancer.

Results produced by this tool are based on studies conducted at large research institutions with surgeons who perform a high volume of prostate cancer procedures. All results must be understood in the context of each patient’s specific treatment plan. Patients and caregivers using this tool should discuss the results with the patient’s physician.
