Background:
Several methods are in use for localization of non-palpable breast lesions prior to excision. The most common is wire-guided localization which is fraught with difficulties and possible complications. Radio-guided localization of non-palpable lesions (ROLL) is a relatively new method which has been never used in our country before. We have for the first time investigated its diagnostic value for localization of non-palpable breast lesions in a teaching hospital in Iran.
