A Lymph Node Biopsy is used to take a small sample of tissue from an enlarged or swollen lymph node, usually located in the neck, armpit, or groin.
Common Indications for Lymph Node Biopsy
Your doctor may request this procedure to:
- Determine why a swollen lymph node isn't going away.
- Check for an infection or an immune system condition.
- See if cancer cells have spread from another part of the body into the lymphatic system.
What happens during the procedure?
You will lie down comfortably. The doctor uses an ultrasound machine to display a live video of the lymph node on a monitor. This ensures they can navigate safely around any nearby blood vessels. After the skin is completely numbed, a needle is guided directly into the node to snip out a tiny piece of tissue.
Do I need to prepare?
Usually, you can eat and drink as normal. You must tell your doctor if you are taking blood thinners, as you might need to stop them for a few days.
How long does it take?
The procedure takes about 20 to 30 minutes. You may be asked to stay in the waiting area for a short time afterward just to ensure you are feeling well.
Will it be painful?
The numbing medicine handles any sharp pain. You will feel some pressure while the sample is taken, and the area might be slightly tender for a day or two.
Conclusion
An image-guided lymph node biopsy is a very safe and accurate alternative to surgically removing the entire node. It quickly provides the crucial information your doctors need to guide your care.
