Image-Guided Breast Biopsy

If your doctor wants to check for cancer, you may receive a breast biopsy at UNC Health Johnston in Clayton or Smithfield. This test uses imaging technology to guide a physician in taking tiny samples of tissue to examine in a lab.

Why Do I Need a Biopsy?

A biopsy reveals more about your health after a mammogram shows a suspicious lump, calcium cluster, or change in breast tissue. Your doctor will recommend the right type of test for you:

• 3D Stereo Tomography Biopsy- Used on patients that have architectural distortion. It allows for the provider to be able to scroll/ roll sliced images and see veins and vessels to aid in avoidance of these during biopsy exams. It decreases potential bleeding complications as well as reduces potential recovery time.
• Magnetic resonance imaging (MRI)-guided breast biopsy – Uses magnets and radio waves to show where to remove a tissue sample
• Stereotactic breast biopsy – Uses mammography equipment to show where to remove a tissue sample
• Ultrasound-guided breast biopsy – Uses sound waves to create pictures of abnormal breast tissue and show where to remove a sample

What to Expect

After your imaging procedure, your doctor cleans the skin on your breast and injects medicine to numb it. Then, the physician makes a tiny nick in your skin and inserts a thin needle into the lump that needs examination. A small vacuum may help pull tissue into the needle.

The doctor may leave a tiny clip in the breast to mark the location of the biopsy in case you need more testing later. This clip will remain in your body permanently, unless you have breast surgery or your doctor determines it needs to come out. It should not cause pain.

How to Prepare

Follow these instructions to make your biopsy go smoothly and get accurate results:

• Do not take blood thinners for five days before the exam
• Avoid wearing deodorant, powder, lotion, perfume, or jewelry on the day of the test
• Tell your doctor if there’s any chance you’re pregnant
• Bring a list of your medications to the exam

Results

A pathologist will examine your tissue sample in a lab and send a report to your doctor. Your doctor will share the results with you and discuss next steps.

Most likely, the unusual breast tissue is benign (not cancer). But if you receive a diagnosis of cancer, count on UNC Health Johnston for expert cancer treatment and support throughout your journey.
