What is a Stereotactic Breast Biopsy?

A stereotactic breast biopsy is a minimally invasive procedure used to sample small breast abnormalities, such as microcalcifications or tiny masses, that are visible on a
mammogram but not always on other imaging. The procedure uses mammography and computer-assisted guidance to accurately locate the area of concern and obtain
tissue samples for diagnostic purposes.
This method is typically used when precise targeting is needed, especially in cases where abnormalities are too subtle to be assessed using ultrasound guidance such as
calcifications or architectural distortion.

What To Expect?

Stereotactic Breast Biopsy

Step 1

The breast is positioned and gently compressed, similar to a mammogram. The skin is then cleansed, and local anaesthetic is administered to numb the area.

Step 2

Computer-assisted mammography is used to locate the area of concern. This helps guide the biopsy needle to the correct spot.

Step 3

A small incision is made in the skin. A specially designed needle is inserted to collect tissue samples from the abnormal area.

Step 4

A dressing is applied over the incision — stitches are not usually necessary. Mild discomfort, bruising or tenderness may occur but usually resolves within a few days. Most
individuals return to light daily activities within 24 hours.

How is this procedure different from other breast biopsies?

Stereotactic breast biopsy is specifically useful for sampling microcalcifications and other findings that are best seen on mammography. In contrast, other biopsy methods, such as ultrasound-guided biopsy, are used when abnormalities are more visible on those respective modalities.
Each approach has specific indications based on the nature and location of the finding, and your doctor will advise on the most appropriate technique.

Will I be awake during the procedure?

Yes. The procedure is performed using local anaesthetic only. This means you’ll be awake, but the breast area will be numbed to minimise discomfort. Most people describe the sensation as mild pressure rather than pain.

How soon can I return to normal activities?

Light activity can usually be resumed the same day. It’s recommended to avoid heavy lifting or strenuous activity for 24 to 48 hours to allow the area to heal properly.
