Intervention (Breast Biopsy)
An Intervention, or Breast Biopsy, is a procedure to examine a specific area of the breast for abnormalities. A very fine needle is guided into a breast nodule to take a small tissue sample, which is then sent to a laboratory for analysis.
HOW DO I PREPARE FOR MY EXAM?
- Please arrive 15 minutes prior to your appointment.
- Take all prescribed medications as directed.
- Wear a two-piece outfit so you can change for the exam more comfortably.
WHAT HAPPENS DURING MY EXAM?
- You will be asked to remove your clothing from the waist up and given a robe.
- Your breast area will need to be visible to your technologist for the exam.
- A technologist will go over the consent form, explain the procedure and answer any questions.
- We will escort you to the exam room where you will be greeted by the radiologist and positioned for your exam. We will perform a pre-scan to document the area of interest.
- The radiologist will administer a generous amount of local freezing and guide a thin tube into the correct location under ultrasound guidance.
- The radiologist will confirm the correct location by viewing the needle from multiple angles.
- Testing of the probe location is sometimes performed by the radiologist, if needed.
- The radiologist will let you know when the procedure has begun. Band-Aids will be placed over treatment areas.
- You will then be checked by the technologist and if there are no concerns, you are free to leave with your driver.
- SPECIAL NOTE: The procedure may vary depending on the biopsy method:
- Fine Needle Aspiration Biopsy (FNA) - A type of ultrasound-guided biopsy in which a very thin needle and syringe are used to remove (aspirate) a small amount of fluid or cells from a lump.
- Ultrasound-Guided Core Biopsy - A special hollow needle is used to take a small cylinder-shaped (core) sample of tissue from a lump or abnormality.
- Stereotactic (Mammography-Guided) Core Biopsy - A needle is inserted into the breast to obtain a tissue sample of the area of interest to be sent for pathologic assessment. This exam is done under mammographic guidance and uses local freezing.
- Wire Localization - A fine wire marks the exact location of an abnormality, usually before a surgeon removes a lump. Once the abnormality is localized within the breast tissue, a local freezing is used to numb the area. A hollow needle is inserted, either by mammographic or ultrasound guidance, and a thin wire with a hook on the end is fed through the needle. Once the wire is correctly place, the needle is removed. The patient would then be ready for surgery.
WHEN WILL I GET MY RESULTS?
