[PRESENT SITUATION AND FUTURE OF ENDOSCOPIC BREAST SURGERY FOR BREAST DISEASE].

Endoscopic breast surgery (EBS) for breast disease has been developed in Japan since 1995. The purpose of EBS is to accomplish the same local control as with conventional breast surgery through small skin incisions. Over the nearly 20-year history of EBS, equipment size has been reduced and procedures have been simplified. Recently, oncoplastic breast surgery, breast surgery using the open-window method, and imageguided nonsurgical ablation have been introduced into clinical practice for local breast treatment. Simplified procedures for EBS should be applied with newly introduced local treatments to achieve local control and expand the indications for those local treatments.
