Background: Preoperative localization of nonpalpable breast cancers requires good coordination between imaging and surgery departments, and insertion of a guide wire can be traumatic for the patient. This study was designed to evaluate the efficacy of intraoperative ultrasound localization of nonpalpable breast cancers directly by the surgeon.
Methods: This prospective study was conducted from June 2006 to October 2006 in 70 patients who underwent surgery for nonpalpable invasive breast cancer.
