Support for Breast Sentinel Lymph Node

Breast sentinel lymph node biopsy is a procedure to determine whether breast cancer has spread to lymph nodes. The sentinel node is the first lymph node to receive drainage from the tumour site. Sentinel node biopsy procedures involve an injection of a radioisotope, technetium-99m at the tumour site. The patient is then imaged using a gamma camera to locate the node, and surgery is performed after imaging, using a gamma probe to detect the radioactive node(s).
