Understanding Stereotactic Breast Biopsy

What is a breast biopsy?

A biopsy involves the removal of a small sample of tissue from the breast so that it can be analyzed for atypical cells. Your physician might recommend a biopsy if there has been an abnormality noted on your mammogram.

Fact: Most breast biopsies reveal the suspicious spot to be benign, or non-cancerous.

What is stereotactic breast biopsy?

Stereotactic breast biopsy is a minimally invasive method of taking a sample of thebreast tissue. Stereotactic refers to using two or more simultaneous X-ray views to target the area with pinpoint accuracy. This method of biopsy allows your physician to remove a sample of tissue quickly, through a small puncture, with little or no discomfort to you.

How is the biopsy done?

You will be asked to lie face-down on a special table. The table has a special opening allowing access to your breast. When the X-ray of your breast have been taken, your physician will cleanse your skin with an antibacterial soap, then numb the skin with a local anesthetic. After your skin is numb, a hollow needle will be advanced to the exact spot indicated by the stereotactic X-ray views, and the suspicious tissue will be withdrawn in the needle. After the tissue has been sampled, adhesive strips will be applied to your biopsy site. The entire procedure will usually take about 15 to 20 minutes.

What are the risks of stereotactic breast biopsy?

Your physician will discuss with you the risks relative to your particular case, but possible complications generally include:

Reaction to the local anesthetic
Infection of the biopsy site

How do I prepare for my biopsy?

Your physician will tell you what you may have to eat or drink before your biopsy, but generally you will be asked to eat lightly and avoid alcohol.

You will be asked to refrain from taking blood thinners, including aspirin and ibuprofen.
Do not wear deodorant or powder to the hospital. These items contain calcium, which can show on your X-rays and confuse the findings.
Wear loose, comfortable clothing to the hospital.
Remember to bring your insurance information and a list of your medications to the hospital.
Do not bring valuables with you to the hospital.
Wear eyeglasses, not contact lenses, to the hospital, if needed.
Arrange to have someone drive you home after your biopsy.

What happens after my biopsy?

Most patients will be discharged from the hospital approximately 30 minutes after their biopsy and may return to normal activities when they are home.

Your physician will give you specific instructions regarding wound care, but generally the wound should be kept dry for the first couple of days, and adhesive strips should remain in place until they begin to peel off; usually 7 to 10 days. Your physician will tell when to expect the results of your biopsy, and you will be asked to call your physician’s office to schedule a follow-up appointment. It is not unusual to have a little bruising around the biopsy site, but call your physician immediately if you have fever or notice drainage or redness at the biopsy site.
