How the Test is Performed
You are asked to undress from the waist up. You wear a robe that opens in the front. During the biopsy, you are awake.
You lie on your back.
The biopsy is done in the following way:
- The health care provider cleans the area on your breast.
- Numbing medicine is injected.
- The doctor makes a very small cut on your breast over the area that needs to be biopsied.
- The doctor uses an ultrasound machine to guide the needle to the abnormal area in your breast that needs to be biopsied.
- Several biopsies may be taken.
- A small metal clip or needle may be placed into the breast in the area of the biopsy to mark it, if needed.
The biopsy is done using one of the following:
- Fine needle aspiration
- Hollow needle (called a core needle)
- Vacuum-powered device
- Both a hollow needle and vacuum-powered device
Once the tissue sample has been taken, the catheter or needle is removed. Ice and pressure are applied to the site to stop any bleeding. A bandage is applied to absorb any fluid. You do not need any stitches after the needle is taken out. If needed, strips of tape may be placed to close the wound.
