Margins refer to the tissue immediately surrounding the prostate that is removed when surgery is done. In order to get all of the prostate, this relatively small amount of surrounding tissue is cut out. It is subsequently examined as part of the post-op pathology process. If cancer is found, then positive margins will be noted. If no cancer is found, then negative margins is the term you will see in a pathology report.
