Common Reasons for Lymph Node Aspiration

Anne Barger, DVM, MS, DACVP, clinical professor in pathobiology at University of Illinois, talks about when to aspirate lymph nodes.

The most common time veterinarians perform lymph node aspiration is when the lymph node is enlarged, Dr. Barger says. But the other time you should aspirate a lymph node is if the animal has another kind of tumor and you're worried the tumor may have traveled to the lymph node or metastasized to the lymph node.
