A breast biopsy is performed when an abnormality is detected and tissue sampling is required for a definitive diagnosis.
Your breast biopsy can be performed using a variety of different imaging techniques. The imaging technique for biopsy is selected by the provider performing the procedure based on your prior imaging results.
Stereotactic breast biopsy This technique uses x-ray images to calculate the location of an abnormality and guides the needle into the area of interest.
MRI guided breast biopsy: This technique uses magnetic resonance imaging to image the location of an abnormality and guides the needle into the area of interest.
Ultrasound-guided breast biopsy This technique uses ultrasound waves to image the tissue and guide the needle into the abnormality. This method does not use any x-ray radiation.
What to Expect
The procedure will start by imaging the area and identifying the abnormality. Your skin will be cleaned and you will be given a local anesthetic to numb the tissue surrounding the abnormality. Using imaging guidance the provider will advance the needle into the abnormality and sampling will be performed. After sampling is complete additional imaging will be performed to access the area sampled. You will be given written instruction for post-procedure care.
