Stereotactic Biopsy
Precise, Minimally Invasive Tissue Sampling
Stereotactic biopsy is a minimally invasive procedure used to obtain tissue samples after an abnormal finding on a mammogram. During the procedure, the patient sits upright in a chair, and the imaging system guides a needle to the targeted area with pinpoint accuracy to obtain a tissue sample. Stereotactic biopsy is an invaluable tool for obtaining tissue samples, allowing for accurate diagnosis and appropriate treatment planning while minimizing risks and discomfort for the patient.

What to Expect
01
Check In & Numb the Area
Arrive 15 minutes early. You'll be escorted to the breast imaging suite, where a local anesthetic is administered and a small incision is made. Additional numbing medicine is available if you feel any sensation.
02
Sample Collection
Using stereotactic, ultrasound, or MRI guidance depending on your case, the radiologist inserts a biopsy needle into the area of concern. You'll feel pressure but should remain still while multiple tissue samples are obtained.
03
Closure & Results
A small marker clip is placed at the biopsy site, the incision is dressed, and two additional mammogram images confirm the clip's location. Samples are sent to pathology, and a radiologist delivers your written results by phone.
How to Prepare
Eat and drink normally before your biopsy. If you take a blood thinner such as Coumadin or Warfarin, let our scheduler know in advance. Wear a sports bra or tight-fitting bra for post-procedure compression, along with comfortable two-piece clothing — a gown or cape will be provided.
Conditions Detected
Stereotactic, ultrasound-, and MRI-guided breast biopsies obtain tissue samples from suspicious areas found on a mammogram, ultrasound, or MRI that aren’t otherwise palpable, helping differentiate between benign and malignant breast conditions with less invasiveness than surgical biopsy.
FAQ
Does a breast biopsy hurt?
You’ll receive a local anesthetic before the procedure, and additional numbing medicine is available if you feel any sensation. Most patients describe feeling pressure rather than pain during sample collection.
How should I care for the site afterward?
Avoid strenuous activity and heavy lifting for the rest of the day. Ice the area for 30 minutes on and off, and over-the-counter medication like Tylenol or Ibuprofen can help with discomfort. Avoid submerging the area in bathwater, pools, hot tubs, or lakes for about a week; showering is fine.
What type of guidance is used for my biopsy?
The type of guidance depends on where your abnormality is best visualized — stereotactic (mammography-guided), ultrasound-guided, or MRI-guided. Your care team will determine the best approach for your specific case.
How will I get my results?
A board-certified radiologist reviews the pathology results and provides a detailed written diagnostic assessment. You’ll receive a phone call from the radiologist or a Breast Health Certified Navigator, and reports are available on the patient portal.
