Lumps or abnormalities in the breast are often detected by physical examination, mammography, or other imaging studies. However, it is not always possible to tell from these imaging tests whether a growth is benign or cancerous.

A breast biopsy is performed to remove some cells—either surgically or through a less invasive procedure involving a hollow needle—from a suspicious area in the breast and examine them under a microscope to determine a diagnosis. Image-guided needle biopsy is not designed to remove the entire lesion, but most of a very small lesion may be removed in the process of biopsy.

Image-guided biopsy is performed when the abnormal area in the breast is too small to be felt, making it difficult to locate the lesion by hand (called palpation).


If an abnormality is clearly visible with the use of Ultrasound, a biopsy can be performed using ultrasound guidance.


  • Discuss any medication you are taking with your physician. You will be asked to discontinue the use of blood-thinning medications, including aspirin and aspirin-like products, prior to your biopsy procedure. If you are taking medications such as heparin, coumadin, Warfarin, or Plavix you will need to check with your doctor who prescribed them about discontinuing their use prior to and after the biopsy day.
  • Wear clothing that is comfortable and easy to remove from the waist up. A gown will be provided for your use.
  • Do not use deodorant, underarm powders or creams before the procedure. They may interfere with the quality of the images taken during your procedure.
  • Eat a light meal before your procedure. Limit your liquids, so that you do not have to use the restroom during the procedure.
  • The majority of patients are able to drive themselves to and from this appointment, but some prefer to have a friend or relative accompany them to their appointment.


  • At the time of your appointment, you will be escorted to a dressing room, provided with a gown and asked to remove your clothing from the waist up.
  • A technologist will position you comfortably on your back on the ultrasound bed.
  • The skin over the area of concern will be cleansed and a local anesthetic administered to numb the area.
  • A tiny nick is made in the skin and the radiologist will insert the biopsy needle into the breast under Ultrasound guidance.  You may experience a sensation of pressure at this point but should not experience any pain.
  • Several biopsy specimens are obtained of the abnormal breast tissue. The specimens will be sent to the pathologist for diagnosis.
  • After the procedure, a sterile bandage will be applied over the biopsy site. No stitches are required.   Most patients experience minimal if any discomfort or bruising following this procedure but we still request that you refrain from strenuous activity for 24 hours.
  • Although the biopsy portion of the procedure is about 30 minutes, you should plan on being at our office for about one and a half hours.
