Ultrasound-Guided Breast Biopsy

What is an ultrasound—guided breast biopsy?

During an ultrasound-guided needle biopsy, a small sample of tissue is removed from the breast, using a hollow needle which is precisely guided utilizing ultrasound imaging.

The tissue sample is then sent to the laboratory for testing.  

Exam preparation

On the day of the exam, you will want to wear a comfortable two-piece garment. We recommend wearing a supportive, soft bra.

You may eat a light meal prior to your procedure and may take your regularly prescribed medications, with the following exceptions.

Do not take any of the following for the three days prior to your procedure:

  • Aspirin or anything containing aspirin
  • Advil®, Ibuprofen or other anti-inflammatory products
  • Coumadin®/Warfarin – you will need to contact your doctor to discuss an alternative therapy  

The exam

During the exam, you will lie on your back or rest on your side against a wedge shaped sponge pillow.

The sonographer is the technologist who will assist with your exam. She will perform a baseline sonogram (ultrasound image) to identify the area of interest in your breast.

Once the exact area of concern in your breast is located, our radiologist will numb the skin of your breast with a local anesthetic, using a small needle.

The radiologist will then place a sampling biopsy device into the skin and guide the device directly into the area of concern.

The sonographer will provide a live image on the monitor to assure accurate placement of the biopsy device. As samples are taken, you may hear a click from the specially designed biopsy instrument; between five to ten tissue samples may be obtained.

The exam takes approximately one hour.

After the exam

After the exam, there may be some bleeding or bruising where the needle was placed. We recommend using cool packs, provided at the time of procedure, on the area affected for the first 24 hours, to minimize swelling and bruising.

You may take a non-aspirin pain reliever, but no aspirin for 48 hours following the procedure. You may have mild discomfort and a small to moderate amount of bruising.

We recommend no strenuous activities for 24 hours.

In addition, a supportive, soft bra, such as a sports bra, may provide additional comfort following the procedure. Some patients find that wearing the bra the first night and the following day is helpful.

The final results of the test are usually available within three working days. To discuss the findings, please contact the physician who referred you for this procedure.

We realize that you may experience anxiety as you await your results.
