How Does a Sentinel Node Injection Procedure Work?
What Will the Patient Experience?
A sentinel node injection procedure will require a very small amount of a radioactive tracer to be injected intradermally and/or subcutaneously around the tumor site or site of interest. The patient will be placed in a sitting or lying position depending on the location of the site to be evaluated. The entire procedure usually takes 15 to 20 minutes.
Typically, the patient may change into a gown before the exam. However, in many cases, the patient will be allowed to wear their own clothing. You may be asked to leave your jewelry and other accessories at home or remove them prior to the exam. These objects may interfere with the procedure. Women should always tell their doctor and technologist if they may be pregnant, pregnant, or breastfeeding before the study. Your doctor will tell the patient how to prepare for their specific exam.
