The impact of the sentinel node concept on the aesthetic outcome of breast cancer conservative surgery

Background The sentinel node (SN) concept has brought numerous advantages to women with breast cancer. Sparing axillary node anatomy and physiology may enhance the cosmetic results of breast cancer conservative surgery, either owing to less breast edema or to a better tolerance to the effects of surgery and radiotherapy. Our aim was to compare the cosmetic outcome of two randomized groups of patients, on a subjective and objective basis.
