Types of Biopsy
Stereotactic Biopsy
When a suspicious abnormality is detected by mammography, a Stereotactic Biopsy may be performed. Stereotactic breast biopsy is a safe and minimally invasive form of breast biopsy. It is used to obtain tiny samples from an abnormal breast mass for examination by a pathologist. This biopsy is performed using a computer and x-ray technology to position a hollow biopsy needle. Biopsies are the only definitive way to confirm whether suspicious breast tissue is normal or abnormal.
Ultrasound Guided Biopsy
Following a breast ultrasound, a biopsy using ultrasound, or sound waves, may be performed. Ultrasound imaging is used to assist with proper positioning of the biopsy needle so a small sample of tissue can be obtained and then analyzed under a microscope. Ultrasound guided biopsy is a highly effective way to evaluate abnormal tissue within the breast.
MRI Guided Breast Biopsy
MRI-Guided Breast Biopsy is usually a preferred alternative to surgical biopsy. It is a recent development and important for diagnosing breast cancer. When a Breast MRI uncovers suspicious areas, an MRI-Guided Breast Biopsy may be performed to help isolate the problem and provide an accurate interpretation by one of our Radiologists.
What should I expect
During an image-guided breast biopsy procedure:
- You will be asked to undress from the waist up and put on a front-opening gown.
- During a Stereotactic and MRI-Guided Breast Biopsy, you will lie on your stomach and the breast will be positioned through an opening in the table where it can be visualized by the imaging technology.
- During an Ultrasound Guided Biopsy, you will lie on your back and an ultrasound probe will be placed on the surface of the skin and used to locate the suspicious area.
- The skin on your breast will be cleansed and a local anesthetic is injected with a very fine needle. You may feel a slight sting.
- A hollow needle will be inserted through the skin. Because of the local anesthetic, most patients report only a small amount of discomfort.
- The Radiologist will use the imaging equipment to precisely guide the needle to the biopsy area where several small samples of tissue may be taken.
- After the needle is removed, a sterile gauze bandage is placed on the skin to prevent bleeding.
- Before leaving our office, you will be given instructions for biopsy aftercare that are specific to your individual needs. Your breast should heal quickly, leaving almost no sign of the procedure.
Please contact us if you have any questions about a biopsy procedure.
How do I prepare
There is no specific preparation for a biopsy, however patients should notify us of any medications they are taking and if there is any chance she is pregnant before a biopsy is performed.
How and when will I know the results
Following a biopsy, one of our Radiologists will interpret an imaging report and a pathologist will analyze the tissue sample taken during the procedure and prepare a report of the findings. Both of these reports will be sent directly to your physician. You should contact your physician to discuss the results of your biopsy. If there is any urgency, your physician is welcome to contact us.
