Gleason score

A grading system for prostate cancer aggressiveness on biopsy.

Gleason scores range from 6 (lowest grade) to 10 (highest). Modern reporting uses Gleason Grade Groups (1-5) for clarity. Higher scores predict more aggressive disease.

What this means for you: Gleason 6 (Group 1) is often eligible for active surveillance, not immediate treatment. Higher grades drive different treatment plans.
