What is ultrasound-guided breast biopsy?
Ultrasound-guided breast biopsy is a procedure used by healthcare providers to collect tissue samples from an area in the breast, using ultrasound imaging to guide the process. This method helps determine whether cancer or other abnormalities are present.
Why is ultrasound-guided breast biopsy performed?
- To evaluate abnormal findings seen on a mammogram or during a clinical breast exam
- To obtain tissue samples for diagnosing breast conditions, including cancer
- To provide information that assists in making treatment decisions
Preparing for your biopsy
- No special preparation required: You do not need to fast or undergo any specific preparations prior to the procedure.
- Consultation: Your radiologist/proceduralist will describe the procedure, explain any potential risks, and answer your questions. Be sure to mention all medications you take and any allergies. Written consent will be obtained prior to the procedure.
Your care team
- Radiologist/proceduralist
- Sonographer
What to expect during the procedure
- Positioning: You will be asked to lie on your back or side, depending on the location of the biopsy.
- Ultrasound imaging: The sonographer will use ultrasound to locate the area of concern in your breast.
- Local anaesthesia: A local anaesthetic will be injected into the skin around the biopsy site to reduce discomfort.
- Tissue sampling: The radiologist/proceduralist will use a thin, hollow needle to take tissue samples. Multiple insertions may be needed to collect enough tissue. You may feel pressure or a brief pinch, but you should not feel pain.
- Duration: The entire procedure generally takes about 20–30 minutes.
Safety and risks
Ultrasound-guided breast biopsy is generally safe, with minimal risks. Possible risks include:

- Infection at the biopsy site
- Haematoma (blood accumulation under the skin)
- Non-diagnostic biopsy
- Non-target injury
After the procedure
- You can usually return to your normal activities immediately, but it's best to avoid heavy lifting for a couple of days.
- Keep the biopsy site clean and dry, and follow any specific care instructions we provide you after your procedure.
- Some tenderness or bruising in the area is normal.
- For full aftercare instructions, see After Your Breast Biopsy.
Your results
