Guide for use:
A list of which lymph nodes are defined as regional lymph nodes for each cancer site may be found in the current edition of the TNM Classification of Tumours, UICC (International Union Against Cancer) and the AJCC (American Joint Committee on Cancer) Cancer Staging Manual.
The number includes all positive nodes regardless of whether they were removed and examined at a single or multiple procedures. For example, for breast cancer, record the sum of positive nodes detected in node sampling/sentinel node biopsy and those removed at axillary clearance.
