Breast Biopsy Stereotactic Core

In This Page:


A breast biopsy is performed to investigate irregularities or abnormalities seen in the breast.  The type of biopsy recommended will be based on the size, location and other characteristics of the abnormalityA Stereotactic Biopsy (Core Biopsy) is a minimally invasive non-surgical interventional breast biopsy that can be performed in an outpatient setting. Stereotactic breast biopsies use x-ray imaging and special computer software to determine the exact location of the abnormality and provide guidance to the biopsy site to remove a sample of the breast tissue. The sample is sent to pathology and examined under a microscope for a diagnosis.

Need to Know

Nice to Know
  • If you take blood thinners, daily aspirin or herbal preparations,your health care provider may adjust or stop this medication a few days prior to the procedure
  • Wear comfortable loose clothing and wear/bring a supportive bra (sports bra)
  • Allow about one hour for your procedure – this includes the pre and post procedure care
  • Inform us of any allergies to latex or lidocaine You will receive post procedure instructions including what to do if you experience swelling and bruising following your biopsy or experience discomfort not resolved with non-aspirin pain relief
  • A radiologist, nurse navigator or your breast surgeon will contact you with the pathology results when they are available, typically within 2-3 business days

 

  • The biopsy will be performed by a specially trained breast interventional radiologist with the assistance of a technologist.
  • The breast will be numbed with a local anesthetic and the staff will closely monitor you for any discomfort. The biopsy equipment can directly inject numbing medication to the biopsy site during the procedure. Inform the Radiologist if you become uncomfortable.
  • The biopsy core needle will be inside your breast for only a few minutes to extract the tissue. Much of the time allotted for the biopsy is to explain the procedure and obtain consent, imaging and targeting of the area and the post biopsy care. Stereotactic biopsies will not leave a scar on your breast and because such a small amount of tissue is removed your breast will not appear any different than before the biopsy.

Why is This Exam Done?

A stereotactic biopsy is performed to  locate and remove tissue samples of  a suspicious mass, micro-calcifications, which are tiny clusters of small calcium deposits in the breast tissue, a distortion in the breast structure or an area of abnormal change in the breast tissue.

What Will Happen During the Exam?

  • You will lie on a specially designed padded table on your stomach with your breast suspended through an opening  in the table
  • The table will be raised and the Breast Interventional Radiologist and Technologist  will work from below to perform the biopsy
  • Your breast will be compressed and images taken to locate the area of concern.
  • Your breast will be cleansed and the radiologist will inject some numbing medicine and make a small cut (nick) over the area to be biopsied so the needle can be inserted.
  • The local anesthetic can be adjusted by the radiologist to alleviate any discomfort during the procedure. Let the staff know if you are uncomfortable.
  • Images will be obtained to confirm that the needle tip is within the lesion before sampling the tissue.
  • Small samples (specimens) of breast tissue will be taken through the needle attached to a vacuum device.  The device will make an audible sound.
  • A very small surgical clip will be left in your breast post-procedure as a future identifier of the area. This cannot be felt, does not cause pain and will not interfere with MRI imaging or any surveillance devices (metal detector).
  • A post procedure mammogram of the breast will be taken to confirm placement of the biopsy clip.
  • Pressure will be  applied to the biopsy site for a few minutes, a bandage is applied and cold/ice packs provided. No sutures (stiches) are needed
  • The tissue samples will be sent for pathology with the results typically obtained within  2-3 business days

What Are the Benefits and Risks?

The benefits of Breast Biopsy (Stereotactic/Core):

  • A stereotactic biopsy procedure is less invasive than a surgical biopsy, leaves little or no scarring and removes far less tissue than a surgical biopsy would
  • The procedure costs less than a surgical biopsy and the results are just as accurate. Stereotactic biopsies can be performed in less than an hour as an outpatient procedure and very little recovery time is required
  • Evaluates calcifications (calcium deposits) or tiny masses that are not visible with ultrasound
Risks you should be aware of:
Complications from a stereotactic biopsy are rare but include:
  • Bruising ,swelling or a collection of blood at the biopsy site (hematoma)
  • Infection - Any procedure where the skin is penetrated carries a risk of infection. Some lesions near the chest wall are difficult to target and may be better sampled with a surgical biopsy
