What is the Gleason Score for Prostate Cancer?

You might be familiar with the term ‘Gleason Score’ if you or a loved one has had a biopsy for prostate cancer. The Gleason score is very important in the diagnosis of prostate cancer because it helps to predict the aggressiveness of the cancer, from low-risk (Gleason 6) to intermediate-risk (Gleason 7) and high-risk (Gleason 8 to 10). Here we explain what the Gleason Score is and how it is used with other important tests and investigations to determine your cancer stage and risk.
