How It Is Done continued...

A vacuum-assisted biopsy is done by a radiologist or a surgeon. This method may be used for a core needle biopsy or a stereotactic biopsy. The biopsy may be done while you sit or lie on an examination table. Or you will lie on your stomach on a special table that has an opening for your breast. A mammogram, ultrasound, or MRI is used to find the exact site for the biopsy.

Your doctor numbs your breast with a shot of local anesthetic. Once the area is numb, a small cut is made in your skin. A hollow probe with a special tip is put into the breast. Tissue is gently vacuumed into the probe. With this type of biopsy, the doctor can take more than one sample without removing the probe.

After the probe is removed, pressure is put on the site to stop any bleeding. The small cut does not need stitches and leaves only a small scar.

A vacuum-assisted core biopsy takes less than an hour.

Open biopsy

An open biopsy is done by a general surgeon, gynecologist, or family medicine doctor. The biopsy may be done in a surgery clinic or the hospital.

You will need to take off all or most of your clothes above the waist. You will be given a gown to use during the biopsy. 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).

An open biopsy can be done using local or general anesthesia. If local anesthesia is used, you may also be given a sedative.

If you have general anesthesia, an intravenous (IV) line will be put in your arm to give you medications. You will not be awake during the biopsy.

After the breast is numb (or you are unconscious), your doctor makes a cut through the skin and into the breast tissue to the lump. If a small wire was placed using mammogram to mark the biopsy site, your doctor will take a biopsy from the area at the tip of the wire.

Stitches are used to close the skin, and a bandage is put on. You will be taken to a recovery room until you are fully awake. You can usually return to your normal activities the next day.

An open biopsy takes about 60 minutes.

How It Feels

You will feel only a quick sting from the needle if you have a local anesthetic to numb the biopsy area. You may feel some pressure when the biopsy needle is put in. After a fine-needle aspiration biopsy, core needle biopsy, or stereotactic biopsy, the site may be tender for 2 to 3 days. You also may have a bruise around the site.
