Oct 13, 2023 · Gleason Score. Gleason scores are a grading system for prostate cancer. Medical pathologists set Gleason scores after studying tissue samples under a microscope. Gleason scores range from 6 (low-grade cancer) to 10 (high-grade cancer). Low grade prostate cancer grows more slowly than high-grade cancer and is less likely to spread (metastasize).
Traditionally, prostate cancer grades were described according to the Gleason Score, a system named for the pathologist who developed it in the 1960s. Dr. Donald Gleason realized that cancerous cells fall into 5 distinct patterns as they change from normal cells to tumor cells. The cells are graded on a scale of 1 to 5.

The main stages of prostate cancer range from I (1) through IV (4). Some stages are split further (IIA, IIB, IIC, etc.). As a rule, the lower the number, the less the cancer has spread. A higher number, such as stage IV, means cancer has spread more. And within a stage, an earlier letter means a lower stage.
When the needle is pulled out it removes a small cylinder of prostate tissue, which is called a core. The doctor will typically remove cores from several different areas of the prostate during a biopsy. The pathologist will give each core (biopsy sample) a number (or letter) in your pathology report, and each core will get its own diagnosis.
