Interventional Breast Procedures
An image-guided biopsy of the breast is performed by taking samples of
an abnormality under some form of guidance such as ultrasound, MRI or
A breast biopsy is performed to remove some tiusse from a suspicious area
in the breast. The tissue will then be examined in the laboratory under
a microscope to determine a diagnosis. This can be performed surgically
or, more commonly, by a radiologist using a less invasive procedure that
involves a hollow needle and image-guidance. Image-guided needle biopsy
is not designed to remove the entire lesion but to obtain a small sample
of the abnormality for further analysis.
How to prepare:
- A consultation is generally scheduled prior to breast biopsies. At this
time, you will be given instructions on how to prepare and an explanation
of what to expect by a radiologist.
- The results of your biopsy will be sent to your physician.
- Arrive 30 minutes prior to appointment time to register and complete necessary
What to expect:
- Image-guided, minimally invasive breast procedures are most often performed
by a specially trained radiologist.
- Breast biopsies are usually done on an outpatient basis.
- Images will be obtained of the area of interest.
- A local anesthetic will be injected into the skin and more deeply into
the breast to numb it.
- A very small nick is made in the skin at the site where the biopsy needle
is to be inserted.
- Tissue samples are then removed. Typically, three to twelve samples are
obtained, depending on the device used.
- A small marker may be placed at the biopsy site so that it can be located
in the future if necessary.
- Once the biopsy is complete, pressure will be applied to stop any bleeding
and the opening in the skin is covered with a dressing. No sutures are needed.
- Mammogram images are obtained after the exam is complete.
- This procedure is usually completed within an hour.
- Results will be sent to the referring physician within 24-48 hours.
