Lumps or masses in the breast are not unusual, and most of them are not
cancerous. Some breast masses can be felt during a breast exam. Others are
detectable only by mammogram-breast X-ray. How a mass is detected does not
determine whether it is cancerous. Breast lumps should be evaluated by a
physician experienced in diagnosing breast cancer.
When a breast biopsy is recommended for an abnormal mammogram finding,
patients may opt for a minimally invasive
alternative to surgery known as image guided core needle biopsy. This is a
tissue sampling technique that does not require surgery.
How is image guided core needle biopsy performed?
The
needle biopsy can be performed using ultrasonic or stereotactic guidance.
During the procedure using stereotactic guidance, the patient lies on her
abdomen on a specially designed exam table. An opening in the table allows
access to the breast. The table is raised and the biopsy is done from below the
table. During the procedure using ultrasonic guidance, the patient lies on her
back on the exam table.
The area to be biopsied is centered in the window of a specially designed
compression paddle. First, mammogram films are taken so the radiologist can
examine the breast tissue to be biopsied. These films are called scout films.
Using a local anesthetic, the radiologist makes a small opening in the skin. A
sterile biopsy needle is placed into the breast tissue area to be biopsied.
Computerized pictures help confirm the exact needle placement using digital
imaging. Tissue samples are taken through the needle. It is common to take
multiple tissue samples (about three to five). This part of the biopsy takes
approximately 15 minutes. Upon completion, sterile strips and a small
adhesive bandage are applied to the skin. The entire procedure takes
approximately an hour. Results are usually available in three to five working
days.
What are the benefits of image guided core needle biopsy?
- Minimal scarring instead of a large incision
- Reduced post-procedural pain
- Potentially lower hospital costs
- Immediate return to work
- Shorter recovery time and immediate resumption of daily activities
How safe is image guided core needle biopsy?
This
procedure is as safe as “open” surgery, when performed by specialists in
this field.
