  1. §this case represents an over-treatment only if happens in more than 15% of the T1 cancers treated
  2. Example:
  3. a) case with tumor size T3, independently on the stage, who undergoes to intervention 85.41 (simple mastectomy) and no linfoadenectomy, is classified as under-treated
  4. b) radical mastectomy (85.45–85.48) in a case with a tumor size less than T4, is always considered as an over-treatment
