A sentinel lymph node biopsy (SLNB) is a procedure in which the sentinel lymph node is identified, removed, and examined to determine whether cancer cells are present. It is used in people who have already been diagnosed with cancer. A negative SLNB result suggests that cancer has not yet spread to nearby lymph nodes or other organs.

This guide for patients is based on the most recent recommendations.
The sentinel lymph node (SLN) is the underarm (axillary) lymph node closest to a breast cancer. During surgery to remove early-stage breast cancer, the sentinel node often is removed and sent to a pathologist who determines if there is cancer in it. Removing just the sentinel node is called sentinel node biopsy or sentinel node dissection.
