From patterns to a group
A pathologist identifies common growth patterns in the sampled tissue. The Gleason score combines predominant patterns; Grade Groups translate that information into five broad categories.
Sampling has limits
A biopsy examines selected tissue, not every cell in the gland. MRI findings, number and length of involved cores, and expert pathology review may add important context.
Ask for the whole report
Have your clinician show you where grade, core involvement, and other comments appear. If the result drives a major decision, ask whether specialist pathology review is appropriate.
Bring these questions
Make the next appointment concrete.
- What is the Grade Group?
- How many cores contain cancer?
- Does the MRI agree with the pathology?
- Would pathology review change confidence?
