  1. CCM conventional conservative method, EAPM endoscope-assisted partial mastectomy, BMI body mass index
  2. Data are column % or mean (standard deviation)
  3. aP value was calculated by χ2 test for categorical variables and Student’s t-tests for continuous variables
  4. bTumor location was defined as; A (upper inner quadrant); B (lower inner quadrant); C (upper outer quadrant); D (lower outer quadrant)
  5. cBased on TNM classification of malignant tumors (14)
