Stereotactic Breast Biopsy

This simple outpatient procedure uses advanced computer technology to pinpoint the precise location of an area of interest seen on a mammogram. During the procedure, the physician removes a small section of the suspicious tissue, then sends the sample to the pathologist for testing and diagnosis. The biopsy procedure only takes a short time to perform. 

What to Expect

The breast biopsy is performed in the outpatient setting in five steps:

  1. The breast is numbed with medicine
  2. Imaging of the breast is taken to identify the biopsy area
  3. A small needle is inserted into breast to retrieve tissue samples
  4. A small amount of tissue is removed
  5. A marker is placed to identify the biopsy site

The marker used to identify the biopsy site is made of titanium and poses no health or safety risk. You will not be able to feel it after it is placed.

After the Biopsy Procedure

After the procedure, avoid strenuous activity and heavy lifting for 72 hours. You may experience some discomfort and notice some bruising in the area where the biopsy was performed. This is a normal part of the healing process and normally disappears within five to seven days.

The results of the biopsy will be available within 24 hours. Your physician will review the pathology report and discuss the findings with you.
