Ultrasound-Guided Breast Biopsy
What is an Ultrasound-Guided Breast Biopsy?An ultrasound-guided breast biopsy is a non-radiation, minimally invasive technique used to gather tissue samples from a breast abnormality discovered during a diagnostic mammogram and/or breast ultrasound. Sometimes these abnormalities turn out not to be a problem. If there is a potential problem, early detection is essential and increases treatment options and the likelihood of successful recovery.
What Will the Procedure Be Like?For your ultrasound-guided breast biopsy appointment, you should plan on being in the center for a couple of hours, which will include all pre- and post-procedure care. The procedure itself will take about 15 minutes. During this time you will be lying still on your back. A female ultrasound technologist will make sure that you are comfortable and then apply a gel that is used to help improve the contact between the hand-held transducer and the skin. The technologist will obtain images by gently pressing and rolling the transducer over areas of the breast or underarms.
Once the abnormality is located, a radiologist will clean the area and inject a local anesthetic into the skin and deeper tissues to numb the area. A very small skin incision – approximately 1/4 inch – will be made.
The radiologist will then use imaging techniques to locate the exact location of the abnormality and extract several tissue samples to be sent to and interpreted by a pathologist. After the tissue is removed, a small metallic marker will be placed. This marker is a reference point for future workups if needed, and confirms that the area of concern has been biopsied. Following your exam, a mammogram will be performed to document the position of the marker.
Some women experience minor discomfort during this procedure. Others experience no discomfort at all.
What Do I Need To Do Before My Procedure?When you schedule your exam, we will review your health history and any medications you are currently taking. On the day of your exam, you may eat and drink normally. Please wear a comfortable, loose fitting two-piece outfit as you will be asked to remove your top prior to the exam. A soft robe will be provided for your comfort. Please refrain from wearing any powder, perfumes, deodorant and/or lotions on your underarms and breasts prior to the procedure. A moist towelette will be provided if you need it and deodorant will be supplied to you after your exam.
In order to provide you with the best care possible, we ask that you please arrive no later than the time requested. For patients who arrive after their scheduled appointment time, we may reschedule your procedure to another day.
What Do I Need To Do After My Procedure?Following your ultrasound-guided breast biopsy, you will need to wear a supportive bra and keep the gauze dressing that covers your incision clean and dry for the first 24-48 hours. You may need to ice the biopsy site following the procedure. Detailed self-care instructions will be provided to you immediately following your biopsy.
Avoid any strenuous activity for 48 hours following your procedure, especially activities that involve repetitive movement of the chest and arms such as lifting, vacuuming, swimming and exercising.
How and When Will I Learn About My Results?Tissue samples obtained during your biopsy will be sent to a pathology lab. Once the results are provided by the lab, which may take a few days, a final report is sent to your referring health care provider, who will then explain the results to you and answer any follow-up questions you may have.
