Reoperative Sentinel Lymph Node Biopsy in Patients With Recurrent Ipsilateral Breast Cancer

Reoperative sentinel lymph node biopsy refers to a surgical procedure performed when there is a need to re-examine the sentinel lymph nodes (SLNs) in patients who have previously undergone breast cancer surgery. The sentinel lymph nodes are the first lymph nodes to which cancer cells are likely to spread from the primary tumor. During the procedure, the surgeon locates and removes the previously identified sentinel lymph nodes using techniques such as lymphatic mapping and injection of a radiotracer or dye. The removed lymph nodes are then examined by a pathologist to determine if there is any evidence of cancer spread.
