Mammography Guided Needle Localization
The Radiologist uses Mammography to accurately place a wire in the tissue
that will guide the surgeon to the area so that the abnormal tissue can
be surgically removed and sent for pathology. This procedure will be scheduled
by your breast surgeon in correlation with the surgical excision.
What to Bring
- Personal ID
- Insurance Card(s)
- Medication list
- A relative or friend to accompany you and drive you home after the procedure
How to Prepare
- Wear comfortable clothing as you will be changing into a gown for procedure.
- Please leave valuable jewelry at home.
- If you wear an on-body device (insulin pump, insulin regulators, Neulasta,
other chemo/insulin devices, etc), you must inform your x-ray technologist.
These devices cannot be in the x-ray room during the exam.
- If there is any chance of pregnancy, please inform the technologist.
- Do not use deodorant, talcum powder or lotion under your arms or near the
breasts. These products may show up as an artifact on the image.
- Your medications will be reviewed prior to your procedure. Your physician
may advise you to stop taking blood thinning medications before your procedure.
What to Expect
- Please plan to arrive at the Mammography Department in the Outpatient Diagnostic
Center 30 minutes prior to scheduled procedure to allow time for consent process.
- You will be asked to sit in a chair during this exam. The affected breast
will be compressed and held in position throughout the procedure. It is
imperative that you do not move once compression is applied.
- Mammography images will be obtained. Once the area of concern is identified,
a radiologist will use a local anesthetic to numb your breast.
- Most women report no pain, but feel pressure and pulling. If you have any
unusual symptoms or sensations, tell the technologist assisting you or
the radiologist so they can help you.
- A needle is placed in the breast and a small wire is threaded through the
needle and inserted into the area of concern. Accurate placement of the
wire is checked by mammogram. The wire is securely taped in place.
- You will be transported from the Mammography department to Same Day Surgery
department to await surgical removal of the wire and breast tissue.
- You will need to allow 60 minutes from registration to completion of test
for the needle localization procedure. Additional time should be allotted
for surgical removal.
- A pathologist will examine the removed specimen and make a final diagnosis.
The results will be sent to your surgeon.
