A needle biopsy is done using a special x-ray to guide the placement of the needle. A small core of tissue is then removed for testing. This test is often used to biopsy very small calcium deposits in the breast or other areas that cannot be done with an ultrasound.
What can I expect?
- The procedure takes about 40-60 minutes.
- You may be sitting in a chair in front of the mammography machine or you may be asked to lie face down on a special biopsy table. Your breast will be cleaned with a special solution. Local freezing will be put into the biopsy area.
- The breast is squeezed between two plates like with a mammogram but, because of the freezing, most women do not find this too uncomfortable.
- A needle is put into the area to remove samples. These samples are sent to the lab to be examined.
- After the test, ice and pressure will be put on the area for 5-10 minutes. You should not do a lot of
vigorous upper body exercise
for the next 48 hours.
- There may be a small amount of bleeding and discomfort in the breast when the freezing wears off.
- You may have some bruising.
- Most women do not have a scar after the biopsy.
How can I prepare?
- You may eat and drink before the test.
- If you take blood thinners, ask your family doctor before the proceudre if the dose should be changed for a short time.
- Do not use powder, deodorants or lotions before the test (metals in these products can show up on the x-ray picture).
- You will be asked to undress from the waist up. It is easier if you wear a two-piece outfit.
- If possible, have someone drive you home after the test.
