Cores may be samples from different areas of the same tumor or different tumors in the prostate. Because the grade may vary within the same tumor or between different tumors, different samples (cores) taken from your prostate may have different Gleason Scores. Typically, the highest (largest number) Gleason Score will be the one used by your doctor for predicting your prognosis and deciding treatment. 

Prostate cancer is a disease that is most successfully treated when it is detected early on.  As the research community explores various methods to detecting the disease, PCEC continues to encourage men to play an active role in their health by looking to those trusted sources of prostate cancer testing – the PSA and DRE.
