Methods From June 2004 to December 2008, 2794 cases underwent minimally invasive surgery under imaged guided mammotome. Results In postoperative pathological diagnosis , 263 cases was invasive breast cancer , 240 cases was ductal carcinoma in situ, 53 cases was atypical hyperplasia, 2238 cases was benign breast lesions. 263 cases of invasive breast cancer were given surgical treatment and adjuvant therapy. 240 cases of ductal carcinoma in situ, 53 cases of atypical hyperplasia and 99 cases of breast papillomatosis were given open surgical procedures. 3 cases were confirmed histologically underestimated. Incidence rate of postoperative active bleeding was 0.11% (3 / 2794), hematoma was 0.39% (11/2794), no incision infection. All patients of benign breast lesions were accepted follow-up by B-type ultrasonic inspection after 6 months. Conclusion Imaged- guided mammotome can perform the minimally invasive surgery for breasts lesion and a determinative histopathologic diagnosis can be obtained.
