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.
breast biopsy is to be done under
local anesthesia, you do not need to do anything else
to prepare for the biopsy.
If the biopsy is to 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 about an hour before
the biopsy. Arrange for someone to drive you home if you will be having general
anesthesia or are going to be given a sedative.
Other tests, such
as blood tests, may be done before your breast biopsy.
How It Is Done
Fine-needle aspiration biopsy
A fine-needle aspiration biopsy may be done by an
family medicine doctor,
radiologist, or a general
surgeon. The biopsy may be done in your doctor's
office, a clinic, or the hospital.
You will take off your clothing
above the waist. A paper or cloth gown will cover your shoulders. The biopsy
will be done while you sit or lie on an examination table. Your hands may be at
your sides or raised above your head (depending on which position makes it
easiest to find the lump).
Your doctor numbs your skin with a shot
of numbing medicine where the biopsy needle will be inserted. Once the area is
numb, a needle is put through your skin into your breast tissue. Ultrasound may
be used to
guide the placement of the needle during the biopsy. If the lump is a
cyst, the needle will take out fluid. If the lump is
solid, the needle will take a sample of tissue. The biopsy sample is sent to a
lab to be looked at under a microscope. You must lie still while the biopsy is
