Abstract: Strategy and value of mastoscopic axillary lymph node dissection for breast cancer        LUO Cheng-yu. Beijing Anzhen Hospital, Capital Medical University, Beijing 100029, China 
Abstract  Conventionally axillary lymph node dissection（CALND) has five inherent defects. The special surgical view of mastoscopic axillary lymph node dissection (MALND) achieves a clear exposure of the anatomical structure of axilla. It avoids the damage to axillary vessel，lymphatic tube and nerve and minimize the occurrence of some complications after  conventionally axillary lymph node dissection（CALND) to the most extend. It achieves the triple effects of minimally invasive，functional and aesthetic. But it differs from laparoscopic surgery as surgeons usually see. The operator must have more skilled laparoscopic technique and be very familiar with axilla anatomy. Surgical process follows the "chronological order" and "spatial order" of "bottom-up，low to high"，from axillary bottom up，to middle and finally to the top. The operation changes the procedures，paths，surgical methods，techniques，view angle，and enlarges the local view inside axilla to traditional breast cancer. Cleaning operation is turned difficult to easy.
