US Guided Breast Biopsy

What is an US Guided Breast Biopsy?

An ultrasound guided breast biopsy is a procedure that utilizes ultrasound and a needle to sample an abnormality in the breast to obtain a diagnosis.

What you can expect during your US Guided Breast Biopsy exam?

After the abnormality is identified on ultrasound by the radiologist, the area of the skin in which the needle will be inserted is cleaned and sterilized. The radiologist numbs the area and carefully inserts the needle into the breast abnormality. Very little pain should be expected when the skin is numbed; otherwise, some minimal pressure may be felt. Once the needle is in correct position for sampling, the samples are taken and a breast clip may or may not be placed in the breast. The breast clip marks the area that was biopsied, so future workup on that same area will likely not be needed. It also aids the surgeon if further surgery is needed following the biopsy.

The biopsy will take about 30 minutes. If lab work is needed prior to the biopsy, this may lengthen exam time.

How can you prepare for your US Guided Breast Biopsy exam?

  • Tell your physician about any medications you are taking (especially blood thinners, such as aspirin or ibuprofen), allergies to anesthetics or bleeding problems.
  • Please inform your physician about any prior breast imaging that may not have been done at the current facility.
  • Inform your physician if you might be pregnant.
  • Undergo blood tests, if required. Sometimes these tests are performed to determine if you have bleeding or clotting problems.

What to expect after your US Guided Breast Biopsy exam?

  • Please resume any medications that were being withheld as a result of your procedure.
  • Avoid any heavy lifting or strenuous activity for the next 24 hours.
  • You may apply an ice pack on and off for 24 hours following the procedure to prevent any swelling or discomfort.
  • If you experience any pain or discomfort, take an Advil or Tylenol every 4 to 6 hours.
  • The pathology results usually take about a week. Contact your referring physician for the results and for any follow-up appointments.
