What is a core needle breast biopsy?
A core needle breast biopsy removes samples of breast tissue using a needle with a special tip. The samples are looked at under a microscope to check for cancer cells.
Why is a core needle breast biopsy done?
A core needle breast biopsy is most often done to check a lump found during a breast exam or a suspicious area found on a mammogram or other imaging.
How is a core needle breast biopsy done?
- You may sit in a chair or lie face up on a table. Or you may lie on your stomach on a table that has a hole for your breast to hang through.
- When the area in your breast is numb, a small cut (incision) is made in the skin.
- Using imaging, the doctor will guide the needle into the biopsy area.
- The doctor will take several samples of breast tissue. This may be done with the needle or with a probe that uses a gentle vacuum to remove the samples.
- A small clip is usually inserted into your breast to mark the biopsy site.
- The needle is removed and pressure is put on the needle site to stop any bleeding.
- A bandage is put on the needle site.
How do you prepare for a core needle breast biopsy?
If you take a medicine that prevents blood clots, your doctor may tell you to stop taking it before your test. Or your doctor may tell you to keep taking it. (These medicines include aspirin and other blood thinners.) Make sure that you understand exactly what your doctor wants you to do.
