A preoperative tumor guiding system for nonpalpable breast cancer using a VATS guiding needle (Hakko Co., Ltd., Tokyo Japan) was reported. It was easy to introduce the guiding needle into breast cancers smaller than 1cm under
ultrasonographic observation. Neither bleeding nor infection was experienced. Wound management was easy and painless. This guiding system is very useful for locating and managing nonpalpable breast cancers even in outpatient
settings.
