Sentinel Lymph Node Biopsy

Biopsy, Sentinel Lymph Node

How It Feels

You may feel a sharp sting or burn from the medicine used to numb the biopsy site or from the dye or tracer. Feeling pressure or warmth during the biopsy is normal, but you should feel little or no pain. If you have pain, tell your doctor. If you feel like you are having an allergic reaction, tell your doctor. This can happen with the dye used in surgery.

If you have general anesthesia, you may feel drowsy for several hours after the biopsy. You may have a mild sore throat from the tube used to help you breathe during the biopsy. Throat lozenges and gargling with warm salt water may help soothe your sore throat. You may get medicine at the biopsy site which will help with the pain for 6 to 12 hours. You may have more pain after this medicine wears off.

The biopsy site may be sore for several days. A small amount of bleeding is normal. Ask your doctor how much drainage to expect. Call your doctor immediately if you have:

• An increase in pain, redness, or swelling at the biopsy site.
• A fever.
• An increase in bleeding or drainage, such as pus.
• Any swelling in your arm.
