Your physician has recommended you for a stereotactic needle-core breast biopsy (vacuum assisted). Cedars-Sinai has a team of experienced mammography specialists led by Donald S. Cohen. MD. The purpose of this procedure is to obtain a tissue sample from the area of abnormality identified on your mammogram and/or breast ultrasound procedure.
Before Arriving for Your Exam
Please eat a light meal at least one hour before your scheduled biopsy appointment.
Take all your usual medication as prescribed by your physician.
Consult your primary physician if you are on Coumadin or blood thinners before scheduling your appointment,
You make take pain medication, such as Tylenol.
Do not take vitamin E for five days before your procedure.
Although we do not anticipate a delay in your scheduled appointment, we recommend that you bring a magazine, book or music player in case you have to wait.
Please leave your jewelry and valuables at home.
You will change into a patient gown, removing your clothes from the waist up.
Before the exam, please inform the technologist and the physician of any allergies you may have.
A technologist and a Cedars-Sinai imaging physician will explain your procedure and answer any questions you may have. The imaging physician will explain the risks and benefits of the procedure before asking you to sign a consent form.
During Your Exam
Breast biopsies are performed two different ways. You may be asked to lie face down on a special table and your breast positioned through a round opening in the table. The table will be elevated so the imaging physician and the technologist can work from below. Or you may be asked to sit upright and the procedure performed with you in a seated position.
The first part of the procedure will seem much like your mammogram. A confirming X-ray will be taken to ensure that the area of the breast containing the abnormality is precisely located for the biopsy.
When the position is confirmed, two stereo X-rays will be taken. They are called stereo because they are images of the same area from different angles. With the help of the computer, the exact position for placing the biopsy needle is determined from these images.
Using this information, the physician will then position the device, which holds the biopsy needle, for the correct angle of entry.
The physician will numb the biopsy area by injecting a local anesthetic into your breast. This will be done with a very tiny needle, and you may feel a slight sting in your breast at the injection site.
After the local anesthetic has taken effect, the physician will insert the biopsy needle into your breast. Another set of stereo X-rays will be taken to confirm proper needle placement. If the needle is not at the abnormality, it will be repositioned and the imaging process repeated.
Once placement is confirmed, the imaging physician will instruct you to hold very still while the tissue samples are taken.
The needle, which now contains the sample, is withdrawn. Several more samples of the area are then taken.
When the physician has confirmed that all the correct samples have been retrieved, a titanium clip will be deployed into the biopsy site. A set of stereo X-rays will be taken to confirm proper clip placement. This clip will mark the biopsy site for future reference.
Following this, the compression will be released from your breast.
The nurse or technologist will apply pressure to the biopsy site for five to 10 minutes to prevent bleeding.
A post-procedure mammogram will be taken to document the deployment of the clip and removal of tissue samples. Afterwards, a dressing will be applied and you will be sent home.
Your exam will take between 60 and 90 minutes.
After Your Exam
The technologist will give you post procedure home care instructions before sending you home.
Your results will be given to you within 48 to 72 hours by the imaging physician or your referring physician when it becomes available.
