Sentinel lymph node biopsy


Some details about sentinel lymph node biopsy

First of all, like all organs of the body, the breast has its lymphatic drainage, which is a kind of cleansing system that carries cancer cells away with the lymph to the lymph nodes.

In the breast, lymphatic drainage is orderly and always carries lymph first to a first relay node, which we call the sentinel node.

Sentinel node biopsy involves injecting a blue dye and a quantity of technetium (radioactive material) into the breast and allowing the dye and radioactive material to travel to the sentinel node.

In this way, with the help of a device that measures radioactivity, we locate the ganglion and remove it, then send it for transoperative study.
