Stereotactic Biopsy uses a computer to analyse information from mammograms. The computer then determines exactly where in the abnormal area to place the needle tip. A small incision is then made in the skin of the breast. and a biopsy needle is guided by the computer to the biopsy site to take a tissue sample. Tissue specimens taken will be sent to the laboratory for microscopic examination.
This procedure is often used to biopsy microcalcifications (calcium deposits).
During the procedure, you will either lie on your side or sit upright on a chair. The area that needs to be tested is centered in the window of a specially designed compression paddle.
After administering a local anaesthetic, the radiologist makes a small incision on the skin. A sterile biopsy needle is placed into the abnormal breast tissue. Computerised pictures help confirm the exact needle placement using digital imaging. Every effort will be taken to minimise any discomfort.
Tissue samples are taken through the needle. It is common for the radiologist to take multiple tissue samples.
The examination may take up to an hour.
If your wound starts to bleed at home, apply firm compression on your wound for about 10 to 15 minutes. If the bleeding continues, please consult your doctor immediately. You may visit the KK Breast Imaging Unit during office hours (8.30am to 5.30pm) or the O&G (24-hour) Clinic after office hours. Please inform the attending doctor that you had a breast biopsy done earlier in the day.
Please attend your scheduled appointment for your post-biopsy consultation after the procedure.
The radiation dose you will receive is very small. As such, there are no side effects from the radiation.
The examination usually does not require hospital admission. It can be performed on an outpatient basis.
If you are admitted to the hospital on the appointment day, please inform the ward staff to contact the KK Breast Imaging Unit.
