Originally, SN biopsy principally concerned cT 1-2 tumours without evidence of axillary lymph node metastases.

Parallel to this evolution various scientific associations are trying to homogenise issues such as radiotracer<span> choice, breast injection site, preoperative imaging standardisation and SN biopsy timing in relation to NST as well as management of non-axillary SN </span></span></span>metastasis (e.g. internal mammary chain). Additionally, RGS is currently used to accomplish primary breast tumour excision either by intralesional radiocolloid injection or by </span></span>radioactive iodine seed implantation which is also employed to target metastatic axillary lymph nodes.
