Sentinel Node Injection
Biopsies are the only definitive way to confirm if breast tissue is benign or cancerous. Abnormalities are examined further by having a sample of tissue, cells or fluid extracted for evaluation in a laboratory.
This procedure is also done the day of surgery and is used to help identify the sentinel lymph node, which is the first lymph node to which cancer cells are likely to spread from the primary tumor. Radioactive tracer will be injected into the skin near the areola.
