Traditionally, prostate cancer grades were described according to the Gleason Score, a system named for the pathologist who developed it in the 1960s. Dr. Dr. Donald Gleason realized that cancerous cells fall into 5 distinct patterns as they change from normal cells to tumor cells.
Gleason scores are a grading system for prostate cancer. Healthcare providers use Gleason score results to set up treatment plans. Gleason scores range from 6 (low-grade cancer) to 10 (high-grade cancer).
