What is an ultrasound-guided breast biopsy?

Advanced ultrasound technology is used to map the precise location of the area of interest in the breast that was seen previously on the mammogram or by ultrasound.

With the use of the technology, the physician is able to remove a small area of tissue. Once the tissue is removed, it is sent to a pathologist who will analyze the tissue for diagnosis.

The procedure takes approximately one hour.

Preparing for the Procedure

On the day of your procedure, you will be asked to undress and will be given a gown to wear.

The technologist will position you lying down on your back or possibly on your side. The physician will be able to look at your breast under ultrasound as the biopsy is performed.

During the Procedure

The skin over the biopsy area will be cleansed with disinfection soap and numbed with a local anesthetic injected into the breast with a small thin needle.

A small incision will be made and the biopsy instrument will be inserted. You may feel some slight pressure during this time and may hear a “click” from the biopsy device.

Once the physician has taken the needed biopsy samples, the biopsy probe is removed from the breast.
