What is Ultrasound-Guided Breast Biopsy?

By DuPage Medical Group Radiology

An ultrasound-guided core breast biopsy is used to take tiny samples of your breast tissue that can be studied under a microscope. During this procedure, an ultrasound helps find the tissue to be removed. This biopsy may prevent the need for an open (surgical) biopsy. 

Things to Know

The total appointment including pre and post biopsy counseling and paperwork will require about 90 minutes. Ultrasound-guided biopsy is a safe procedure, however It does have some rare risks. These include bleeding, infection and failure to remove the right tissue. 

The Procedure

During an ultrasound-guided breast biopsy you undress from the waist up and put on a gown that opens in the front. While lying on your back on an exam table, the area of tissue to be biopsied is located with ultrasound. The skin on your breast is cleansed and you will be given a small injection of local anesthetic into your breast. This may sting slightly. A small incision is made in your skin. The biopsy device is inserted into the breast under ultrasound guidance, and cores of tissue are removed. In addition, a marker may be placed at the site where the tissue was removed. This is to mark the area of biopsy internally and also serves as a marker for future reference. After the biopsy device is removed, steri-strips are placed on your skin. An ice pack, which fits inside your bra, will be placed at the biopsy site. Your biopsy site will be checked, and you will be able to go home shortly after the procedure.
