Breast Biopsy

(continued)

How To Prepare continued...

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.

The needle is then removed. Pressure is put on the needle site to stop any bleeding. A bandage is put on. A fine-needle aspiration biopsy takes about 5 to 15 minutes.

Core needle biopsy

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 small cut is made in your skin. A needle with a special tip is put into the breast tissue. The doctor will take 3 to 12 samples to get the most accurate results.
