A Gleason score is part of a classification system for prostate cancer, based on the microscopic appearance of cancer cells, samples of which are taken during a prostate biopsy. Your Gleason score is used to predict the seriousness of the prostate cancer and the need for prostate cancer treatment. Gleason scores range from 2 to 10, and are derived by adding the 2 most prevalent cancer grades, which range from 1 to 5. A lower score indicates that the cancer is less aggressive.

A helpful note to our readers: The correct spelling of this male gland is PROSTATE. There is no letter R. Here are some common misspellings to watch out for when you are searching for reliable information online: prostRate, (prostrate means to lie face down, it does not refer to the body part), prostRate disorders, prostRate cancer, prostRate disease, enlarged prostRate, prostRate treatment, prostRatitis, and so forth. All of these are incorrect spellings. We hope this helps you avoid confusion.
