The amount of normal tissue that should be excised during breast conserving surgery is widely debated. Tissue adjacent to breast tumors, although histologically normal, possesses many of the molecular abnormalities found in tumor tissues. Here, we propose that the ideal physical distance for a surgical margin may not be universal. Rather, an adequate surgical margin likely varies from patient to patient, depending on the biology of the tissue that remains after surgery. J. Surg.
