Breast Biopsy

(continued)

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.

If a 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 biopsycamera.gif may be done by an internist, 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 done.
