Lymph Node Biopsy

During a lymph node biopsy procedure, all or part of a lymph node is removed from the body. It’s then sent to a lab to be tested. This video covers several types of lymph node biopsies. Lymph nodes are located throughout your body. These small organs help fight infections and diseases. A lymph node biopsy can help doctors: • Diagnose cancer or another condition • Tell if cancer has spread to the lymph nodes • Determine the best treatment for cancer A sentinel lymph node biopsy may be done to see if cancer has spread. This procedure finds and tests the lymph nodes where cancer would probably have spread first. These lymph nodes are called sentinel nodes. As part of a sentinel biopsy, a blue dye or radioactive tracer is injected into the original tumor. Then, an imaging test is used to see which lymph nodes the dye or tracer goes to first. Those nodes are the sentinel nodes. A sample may be collected from the sentinel nodes using a needle biopsy or an open biopsy. A lymph node biopsy can take anywhere from 10 minutes to an hour. You can usually go home the same day.
