Sentinel lymph node (SLN) biopsy allows a more detailed examination of a smaller number of lymph nodes in patients with clinically node negative breast cancer. Immunohistochemistry detects small tumour burden not routinely seen on haematoxylin and eosin (H & E). The significance of such findings remains to be fully elucidated.
