Core needle biopsy
Informed by recognized medical guidance
Overview
A core needle biopsy is a medical procedure that uses a special hollow needle to remove a small sample of tissue from a lump or abnormal area in your body. This sample is then examined under a microscope to help diagnose conditions, most often cancer. It gives a larger, more detailed sample than a fine needle aspiration.
