Ultrasound–Guided Breast Biopsy

Ultrasound–Guided Breast Biopsy

A specially trained radiologist most often performs image-guided, minimally invasive procedures, such as ultrasound-guided breast biopsies. This procedure is used to obtain a more precise diagnosis of suspicious tissue changes that have been located in the breast.

What to expect

  • You will be given a local anesthetic before the procedure.
  • You will be positioned lying face up on the examination table or turned slightly to the side.
  • The sonographer or radiologist will press a transducer to your breast to locate the suspicious tissue.
  • A very small nick is made in the skin at the site where the biopsy needle is to be inserted.
  • The radiologist will insert the needle and advance it directly into the mass.
  • Removal of the tissue samples takes about 20 minutes. Afterward, you will be asked to keep tight pressure on your breast for about 20 minutes while lying down.
  • After the exam, there will be some bleeding where the needle was placed. The incision will be bandaged and a cold pack will be applied to relieve any swelling.
  • You may take a non-aspirin pain reliever, like Tylenol, to help alleviate any discomfort.
  • You may notice some bruising of the area, which should resolve within five to seven days.
  • You may resume normal activities after the exam, however you should take it easy for about 24 hours after the biopsy is performed.

How to prepare for the exam

  • Wear a comfortable two-piece outfit.
  • You may eat a light breakfast.
  • Discontinue use of aspirin or blood thinners for at least one week prior to the exam.
  • Do not use any powder, deodorant, lotion, or perfume on the day of the procedure.
  • Arrive 30 minutes before your scheduled exam to allow time to change your clothes and register.
