A Gleason score of 7 is a medium-grade cancer, and a score of 8, 9, or 10 is a high-grade cancer. A lower-grade cancer grows more slowly and is less likely to spread than a high-grade cancer. Doctors look at the Gleason score in addition to stage to help plan treatment.What does a Gleason score of 3 4 7 mean?
