Although pathologic assessment of margins for tumor is standard practice in evaluation of lumpectomies and mastectomy specimens, the obstacles for obtaining consistently accurate results are the very nature of the tissue (adiposity), the extent of in situ component [ 5, 6 ], and the insidious manner of tumor infiltration and tumor multifocality.

A resection margin or surgical margin is the margin of apparently non-tumorous tissue around a tumor that has been surgically removed, called resected, in surgical oncology. The resection is an attempt to remove a cancer tumor so that no portion of the malignant growth extends past the edges or margin of the removed tumor and surrounding tissue. These are retained after the surgery and examined microscopically by a pathologist to see if the margin is indeed free from tumor cells.
