In recent years, laparoscopic breast cancer surgery has received wide attention. It has advantages of minimal invasiveness, clear anatomical exposure, and good aesthetic effects. Based on these advantages, we propose whether laparoscopy is suitable for breast-conserving surgery for breast cancer. The standard procedure of laparoscopic breast-conserving surgery is unclear. More high-quality clinical studies are required to ensure the efficiency of cure. Also, less scars and breast preservation has becoming more and more important for patients' acceptance to the treatment. Therefore, we intend to conduct a multi-center, open, productive, randomized controlled study comparing the safety and cosmetic effects of endoscopic breast-conserving with traditional open breast-conserving surgery.
