Abstract: The tumor-free principle is a surgical concept and measure，which aims to reduce tumor implantation and recurrence. The route of hysterectomy due to benign uterine disease includes transabdominal hysterectomy，laparoscopic hysterectomy（including robotic surgery），and vaginal hysterectomy，and the tumor-free defensive measures should be taken，including protection of incision，preventing the leakage of diseased tissue，enlarging the scope of resection in time，prevention of contamination of surgical instruments by diseased tissues，complete resection of adjacent diseased tissue，and postoperative flushing of the surgical field. Tumor-free defense should also emphasize the cooperation between doctors and nurses，and be carried out  through the whole process from pre-operation to post-operation.

Key words: hysterectomy, tumor-free defense, benign uterine disease
