Breast Biopsy/Mammotome

These procedures involve the use of a computer-assisted positioning device for accurate placement of a needle into the lesion, so it can be sampled by obtaining a core of the tissue. In many instances, this replaces the conventional open surgical biopsy.

Preparing for Biopsy

  • Do not take blood thinners, aspirin or any medication containing Ibuprofen such as Advil or Motrin for 7 days prior to the procedure. Use Tylenol as a pain reliever if needed.
  • There are no dietary restrictions.
  • Do not use bath powders or oils on the breast.
  • If the patient has a known history of cardiac valve disease, which
    requires antibiotic treatment before dental cleanings or procedures,
    please contact your referring physician. The patient may need to be
    pre-medicated before the procedure is performed.
  • It is essential that we have the patient’s mammograms. Please call our office the day before the appointment to verify that we have the films. If we do not have the mammograms, the exam will be rescheduled.
  • We advise that the patient bring someone to drive them home.
  • We ask the patient to arrive 15 minutes prior to the scheduled appointment to complete the registration process.


During the biopsy

During the Biopsy

The patient will lie face down with the breast positioned comfortably through an opening on the biopsy table. A technologist will take x-rays of the breast that requires biopsy using a computerized mammography machine. This will help locate the lesion and calculate where the radiologist should place the needle. Next, the radiologist will inject a local anesthetic into the area and make a small incision where the needle will be placed. The needle will stay in while the samples are taken.

The procedure takes about 1 hour and most patients experience very little discomfort (usually just a small sting from the local anesthetic). Some patients may feel a little pressure at the moment the biopsy is taken, but the discomfort is minimal. After the procedure, a small band-aid is put on the breast.

Following the Biopsy

If the patient must return to work immediately they may do so, as long as the activity is not strenuous. The tissue samples will be sent to pathology. The pathology report is usually sent to our office within one week of the patient’s appointment. Once the pathology report has been received, it will be given to the radiologist who will review the report and films and dictate a letter to the referring physician stating specific recommendations.
