Abstract

Imaging studies in mammary pathology now provide detection of clinically non palpable lesions whose study requires percutaneous biopsy. If histopathological study is insufficient, suspect or confirms malignancy, surgical resection is necessary. This procedure poses a challenge for the oncology surgeon who has at his/her disposal several techniques, the most widely used being spiral harpoon marking. Another alternative, in use for more than ten years, is ROLL (radio guided occult lesion localization) which not only serves as an adequate weapon to be used against non palpable lesions, but also provides advantages over other, resulting in lower resection volume and lower positive margin incidence. This article describes the ROLL technique used for the localization of non palpable breast lesions.
