If you’ve recently been diagnosed with prostate cancer, you may have received a pathology report with something called a Gleason score. For many patients, seeing this number can feel confusing and overwhelming at first.
At Conrad Pearson Clinic, one of the most common questions we hear is: “What does my Gleason score actually mean?”
The good news is that your Gleason score is simply a tool doctors use to better understand how prostate cancer may behave and what treatment options may be best for you.
What Is a Gleason Score?
A Gleason score is a grading system used after a prostate biopsy. During the biopsy, small tissue samples are taken from the prostate and examined under a microscope by a pathologist.
The pathologist looks at how different the cancer cells appear compared to normal prostate cells. The more abnormal the cells look, the more likely the cancer may grow or spread more quickly.
The Gleason score helps your doctor determine:
- Whether the cancer is low, intermediate, or high risk
- How aggressive the cancer may be
- What treatment options may be recommended
- Whether active surveillance may be appropriate
How Is the Gleason Score Calculated?
The score is made up of two numbers that are added together.
The pathologist identifies:
- The most common pattern of cancer cells
- The second most common pattern
Each pattern receives a grade between 1 and 5. Those numbers are then added together to create the Gleason score.
For example:
- 3 + 3 = Gleason 6
- 3 + 4 = Gleason 7
- 4 + 3 = Gleason 7
- 4 + 4 = Gleason 8
This can sound complicated, but here’s the important thing to understand:
The first number matters most because it represents the dominant type of cancer cells seen in the biopsy.
So while both 3+4 and 4+3 equal 7, a 4+3 cancer is generally considered more aggressive because more of the higher-grade cells are present.
What Do the Different Gleason Scores Mean?
Gleason 6 (Low Risk)
A Gleason 6 prostate cancer is considered low risk and often grows very slowly.
Many men with Gleason 6 disease may not need immediate treatment. Instead, they may be candidates for active surveillance, which involves:
- Regular PSA testing
- Imaging such as MRI
- Follow-up biopsies when needed
For some patients, monitoring the cancer carefully may be the safest and most appropriate option.
Gleason 7 (Intermediate Risk)
A Gleason 7 is considered intermediate-risk prostate cancer.
- 3+4=7 is generally considered more favorable
- 4+3=7 may behave more aggressively
Treatment recommendations for Gleason 7 prostate cancer may include:
- Surgery
- Radiation therapy
- Focal therapy
- Active surveillance in select patients
Your doctor will look at several factors before recommending a treatment plan.
Gleason 8–10 (High Risk)
Gleason scores between 8 and 10 are considered high-risk prostate cancer. These cancers are more likely to grow quickly or spread outside the prostate.
Patients with higher Gleason scores may require more aggressive treatment and closer follow-up care.
Your Gleason Score Is Only One Piece of the Puzzle
While the Gleason score is important, it is not the only thing doctors consider when evaluating prostate cancer.
At Conrad Pearson Clinic, providers also look at:
- PSA level
- MRI findings
- Cancer stage
- Biopsy results
- Age and overall health
- Family history
- Personal treatment goals
This helps create a treatment plan tailored to each individual patient.
New Advances in Prostate Cancer Testing
Today, prostate cancer care goes beyond what can be seen under the microscope alone.
Advanced tests are available to analyze specific genes within the cancer tissue to help predict whether the cancer is likely to behave aggressively or remain slow-growing.
These tests can also provide additional information that helps patients and providers make more informed treatment decisions.
What Should You Do After Receiving Your Gleason Score?
First, take a deep breath. Receiving a Gleason score does not automatically mean you need immediate treatment or surgery.
Most prostate cancers are highly treatable, especially when detected early. The most important next step is meeting with an experienced urologist who can explain your results and help you understand all available options.
At Conrad Pearson Clinic, our team provides advanced prostate cancer diagnosis and treatment for patients across Memphis and the Mid-South. We are committed to helping patients understand their diagnosis clearly so they can move forward with confidence and peace of mind.
