The Procedure

During a stereotactic biopsy, small samples of tissue are removed from the breast using a hollow needle which is precisely guided to the suspicious location via X-ray mammography and computer coordinates. A woman undergoing the procedure lies face down on a specially designed table; the breast will be slightly compressed and held in position during the procedure. Usually between three and five small tissue samples are removed. The examination can take from thirty to forty-five minutes and only local anesthesia is used. Most women report no pain and little discomfort. There is no scar at the end of the procedure.

The Indications for the Procedure

A well-defined, nonpalpable solid mass that appears benign.
- in women with strong family histories of breast cancer
- when the mass is relatively large (greater than 5 mm in size)
Lesions exhibiting characteristics associated with cancer.
- clustered microcalcifications
- irregular or asymmetric densities
Areas of architectural distortion.
Prior surgical sites with recurrent nonpalpable mass or calcification.
The patient or physician prefers non-surgical evaluation.

When Surgical Evaluation Is A Better Alternative

Nodules of less than 5mm in size. When nodules are completely removed by stereotactic biopsy, surgical follow-up may be compromised.
Diffuse calcification. These are difficult to target with stereotactic biopsy.
Lesions near the chest wall. This location is a limitation of the procedure.

Before the Procedure

Women should avoid using talcum powder or deodorant and discontinue aspirin or blood thinners 3 days in advance of the procedure.

Follow-Up
Some patients require a follow-up mammography six month after biopsy and some are recommended to resume routine follow-up.
