P247 Radiofrequency as a method of localizing occult breast lesions

Introduction: The number of advanced breast cancers has decreased due to the detection of early nonpalpable breast cancers through the screening program. One of the obstacles to performing breast-conserving surgery is the precise localization of non-palpable breast lesions, especially considering the logistical issues of wire localization. Following the introduction of a novel method (RFID), we aimed to determine whether the re-excision of positive margin increased and whether it depended on RFID position.
