Lymph node biopsy
Alternative names:
biopsy of the lymph nodes
How the test is performed:
The test is done in the hospital. There are 2 ways the sample may be obtained: a needle biopsy or an open biopsy. A needle biopsy involves inserting a needle into a node to obtain the sample. You will be asked to lie on the examination table. The biopsy site will be cleansed, and a local anesthetic will be injected. The biopsy needle is then inserted into the node. A sample is removed, pressure is applied to the site to stop the bleeding, and a bandage is applied.
An open biopsy consists of surgically removing a part or all of a node. You will be asked to lie on the examination table. The skin over the biopsy site is cleansed, and a local anesthetic is injected (occasionally, a general anesthetic is given). A small incision is made and the entire lymph node or a part of the lymph node is removed. The incision is then closed with stitches and bandaged. The biopsy is then sent to the laboratory for examination.
How to prepare for the test:
Tell your health care provider about any drug allergies, which medications you are taking, if you have bleeding problems, and if you are pregnant. You must sign a consent form.
Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:
How the test will feel:
When the local anesthetic is injected, there will be a prick and a mild stinging. The biopsy site will be tender for a few days after the test.
Why the test is performed:
The test is used to help determine the cause of lymph node enlargement (swollen glands). It can also determine whether tumors in the lymph node are cancerous or noncancerous.
