Arm morbidity following sentinel lymph node biopsy or axillary lymph node dissection: A study from the Danish Breast Cancer Cooperative Group

Node negative patients operated with sentinel lymph node biopsy have less arm morbidity compared with node negative patients operated with axillary lymph node dissection. Node positive patients who had a secondary axillary lymph node dissection after sentinel lymph node biopsy had no difference in either objective or subjective morbidity compared with node positive patients having a one-step axillary dissection.
