What is the difference between core needle and fine needle aspiration?
There are a few differences between the two. A core needle biopsy is done with a larger needle and a small incision is made in the skin above the area to be biopsied. The incision allows for easier insertion of the needle, but is not needed when performing an FNA because the needle used is very thin. Refer to this table comparing fine needle aspiration and core needle biopsy for more detailed information.
