An ultrasound-guided breast biopsy is performed by using ultrasound to locate the area in question. Unlike procedures that require the use of X-Ray, ultrasound-guided biopsy requires no exposure to radiation. This procedure is very useful when suspicious changes can’t be seen by a mammogram or an ultrasound. This type of biopsy is a minimally invasive way to obtain a sample of breast tissue for further diagnosis. It is also faster and less painful than traditional surgery biopsy.
YOUR MEDICATIONS
It is extremely important that you inform your healthcare provider regarding all medications you are currently taking. This includes vitamins, herbs, and over-the-counter medications.
HOW WILL I GET THE RESULTS?
A pathologist will examine the tissue specimens and will report the findings to your doctor, usually within 3-5 working days.
The results of your biopsy will be made available to you through your designated healthcare provider or doctor.
WHAT TO EXPECT DURING YOUR ULTRASOUND GUIDED BREAST BIOPSY
There is no special preparation required prior to having an ultrasound-guided breast biopsy. It is recommended that a comfortable two-piece outfit be worn, because you will be undressing from the waist up. Before you arrive, the radiologist will have studied your imaging exams to become familiar with the location of the abnormality.
The procedure itself will usually take less than an hour and generally causes mild to no discomfort. The first part of the procedure will seem much like your original ultrasound. While lying on your back or turned slightly on your side, your breast will be scanned to find the abnormality. Then the technician will mark your skin over the area in question. The radiologist will clean your breast and then numb the area with enough anesthetic to insure that you will not feel discomfort during the procedure. The anesthetic used is very similar to what is used at the dentist. There is a tiny stick on the outer skin and you may feel a sting as the medication enters the tissue. After the anesthetic has taken effect, the radiologist will make a very small incision in the skin where the biopsy needle will be inserted. Using ultrasound guidance, a hollowcore needle or vacuum assisted needle is placed in the breast, guided to the location of the mass and specimens are collected.
Once the placement of the needle is confirmed, you will be asked to remain motionless while the samples are taken. Ultrasound transmits a visual image during the entire procedure, enabling the radiologist to view the procedure on a video screen and ensure accurate placement of the needle.
There are two methods used to collect the tissue sample: one is the core needle biopsy method - the needle holds the tissue sample until the needle is withdrawn and the sample is placed in a specimen container. This may be repeated multiple times. The second method uses a vacuum-assisted device (VAD). Once the needle is in place a vacuum is used to pull the tissue into the specimen collector.
When the procedure is complete, the technician will apply pressure to the biopsy site for several minutes. Then a dressing will be applied.
