Ultrasound-Guided Core Needle Biopsy
ultrasound-guided core needle biopsy is a procedure done to remove
several samples of breast tissue that appear abnormal. The tissue
sample is then examined in the laboratory for signs of disease.
- You may eat a light meal at home before your scheduled appointment.
- Avoid aspirin or aspirin-like medications (ibuprophen, Motrin, etc) for one week before the biopsy.
- Notify your physician/nurse practitioner if you are on a prescription blood thinner such as Coumadin.
- You may take your prescription medication the day of the test (except blood thinners).
- Wear a two piece garment since you will need to remove your clothes from the waist up for the procedure.
What to Expect
- You will lie on an exam table.
- The physician/nurse practitioner will place warm gel onto your breast and rub a transducer/probe around to locate the area to be biopsied.
- A local anesthetic (Lidocaine) will be injected in the breast to numb the skin. The injection feels like a bee sting.
- We will then remove several samples of tissue with a needle.
- Pressure is applied over the biopsy site for a few minutes to stop any bleeding.
- The test takes about 45 minutes for one breast lump. With more than one lump, the test will take longer.
After the Procedure
- When the procedure is done, steri-strips (paper-like tape) will be applied on the skin incision.
- You may use an ice pack that fits inside your bra.
home, continue to apply ice to your breast to relieve swelling and
reduce bruising. Apply ice for 20 minutes at a time with 30 minutes
between ice applications. Do not apply ice directly to the skin.
- Bruising may occur at the biopsy site, and should subside within five to seven days.
- Avoid strenuous activity and lifting over 5 pounds for 24 hours after the test.
- You may resume your normal daily activities as long as you are doing well.
- The laboratory will notify your doctor of the biopsy results within 3 to 4 working days.
Call Your Doctor if You Have:
- Persistent bleeding or drainage.
- Excessive swelling, redness or warmth at the biopsy site.
- Pain that becomes severe.
- Your doctor/nurse practitioner will have the biopsy results within 3 to 5 working days. Call your doctor if you have not received the results within 1 week.
