Surgical removal of multiple lymph nodes from the armpit area to determine cancer spread and provide regional disease control.
Full Definition
Axillary lymph node dissection (ALND) is a surgical procedure involving the removal of Level I and II lymph nodes from the axilla (armpit region). This procedure is performed when cancer has spread to the sentinel lymph nodes or when sentinel node biopsy is not feasible. ALND provides important staging information and regional disease control but carries higher risks of complications including lymphedema, nerve injury, and decreased shoulder mobility compared to sentinel lymph node biopsy alone. Current guidelines aim to minimize the use of ALND when possible.
Usage
Usage note: Use ALND abbreviation only after full term introduction; distinguish from sentinel node procedures.
