Excisional Biopsy with Needle Localization to Evaluate Abnormal Mammograms

Your surgical procedure has two steps:

Step 1. Needle Localization is a way to mark an abnormal area that was seen on your mammogram but is too small to feel.

1a. After reporting to the surgical reception desk, you will be escorted to Radiology. Your skin will be cleansed and anesthetized. The radiologist will use your mammogram to guide a small needle and wire into the abnormal area.

1b. A new mammogram will be done to verify the wire is in the proper place. Sometimes the abnormal area disappears, indicating it was a fluid-filled cyst. If this occurs, you will not need a biopsy and will go home.

1c. You will be moved to a comfortable place to wait for your excisional biopsy.

Step 2. Excisional Biopsy removes the tissue in the abnormal area, now marked by the wire.

2a. You will be moved to an Operating Room.

2b. Your surgeon will anesthetize the area over the wire and make an incision to remove the abnormal tissue. The tissue will be x-rayed to confirm the abnormal area was removed, then sent for testing.

2c. Your incision will be closed with sutures, which are under the skin and dissolve on their own, then bandaged.

2d. You will learn how to take care of your incision before you leave the hospital.

2e.  The most common risks of the surgery are bleeding and infection.  Your surgeon will  have discussed this with you.

Your Test Results

We will have the test results (pathology report) on your biopsy in about one week. Your doctor will discuss your test results with you at your follow-up visit.


After Your Surgery



Call us immediately at 413-794-4262 if you have any of the following:

Redness, pus, or enough blood to soak the bandage at the incision.

Severe pain that will not go away after taking your pain medicine.

Temperature over 101.5°F.



  • Driving. We do not recommend you drive until after you are evaluated by your doctor during your follow-up visit.

    Activity. Avoid activities that increase breast movement or have repetitive arm movement.

    Pain. Some pain is normal. You will receive a prescription for a strong narcotic pain medicine. If you prefer a milder pain medicine, take 2 extra strength Tylenol (acetaminophen) every 4 to 6 hours. During the first 48 hours, avoid medicines that can cause bleeding (like aspirin or Motrin).

    Clothing. Wear a bra at all times during the first 48 hours after surgery. This prevents movement that causes pain and bleeding.

    Showering. You may shower 48 hours after your surgery. (Remove the outer bandage first; afterwards, pat dry.)

    Sleeping. Avoid sleeping on the side of your operation since this may cause more swelling.
    Wear your bra.

    Bruising. Bruising is normal. This will go away over a couple of weeks. 

    Swelling. If your breast feels swollen, you may place an ice pack over the incision.

Your Follow-Up Care

Checking Your Incision. A little blood on the bandage is normal. If the bandage becomes soaked with blood or other fluids, please call our office immediately.


Removing Your Bandage. Unless otherwise directed, you may remove the outer bandage
24 hours after surgery.

When you remove the bandage, there will be
a row of small white tapes directly on the incision. Please, do not remove these strips
of tape before your follow-up visit with your doctor.


Keeping Your Incision Clean. After you remove the bandage, you may get the incision area wet (48 hours after surgery). Pat the incision dry.

Do not take baths that would soak the area until after you have been evaluated by your doctor during your follow-up visit.

Occasionally, you may notice a hardened area where the tissue was removed. This is normal. As the area heals it first becomes hard, then softens over the next several months.
