Breast cancer is the most common cancer diagnosed in females worldwide. In the United Kingdom, Cancer Research UK estimated that there were 55,122 new cases of breast cancer in 2015 and 11,563 deaths from breast cancer in 2016. 1 Due to advances in imaging technologies and national breast screening programmes, approximately 25-35% of detected breast tumours are non-palpable at diagnosis. 2,3 The accurate identification of non-palpable lesions pre-and intraoperatively, together with the precise localisation of the tumour with adequate resection margins, are crucial in the quality of surgical care and will affect the oncological and cosmetic outcomes. Wire guided localisation (WGL), where a guide wire is placed in situ under ultrasonographic or radiographic control, has been the standard technique for guiding the surgical resection of non-palpable breast tumours. However, this technique can cause discomfort and inconvenience to the patient.
