How To Prepare continued...
You will be asked to sign a consent form that says you understand the risks of the test and agree to have it done.
Talk to your
doctor about any concerns you have regarding the need for the biopsy, its
risks, how it will be done, or what the results will mean. To help you
understand the importance of the biopsy, fill out the
medical test information form(What is a PDF document?).
If you take a blood thinner, you will
probably need to stop taking it for a week before the biopsy.
lymph node biopsy will be done under
local anesthesia, you do not need to do anything else
to prepare for the biopsy.
If the biopsy will be done under
general anesthesia, follow the instructions exactly
about when to stop eating and drinking, or your surgery may be canceled. If
your doctor has instructed you to take your medicines on the day of surgery, do
so using only a sip of water. An
intravenous line (IV) will be put in your arm, and a
sedative medicine will be given before the biopsy.
Arrange for someone to drive you home if you are going to have general
anesthesia or will be given a sedative.
Other tests, such as blood
X-rays, may be done before the lymph node
How It Is Done
Fine-needle aspiration biopsy
A needle biopsy of a
lymph node near the skin is usually done by a
radiologist, or a
general surgeon. A needle biopsy of a lymph node
deeper within the body is usually done by a radiologist using a
CT scan or
ultrasound to help guide the needle. The biopsy may be
done in a surgery clinic or the hospital.
You may need to take
off all or some of your clothes. If needed, you will be given a cloth or paper covering to use during the biopsy.
Your doctor numbs the area where the needle will be inserted. Once the area is numb, the
needle is put through the skin and into the lymph node. You must lie still while the
biopsy is done. The biopsy sample is
sent to a lab to be looked at under a microscope.
