What is the definition or description of: needle biopsy?
A doctor has provided 1 answer
FNA: A needle biopsy (or fine needle aspiration) is a procedure whereby a thin needle (similar to one the is used for drawing blood), is guided into a lesion and cells are obtained and then placed immediately onto a glass slide for evaluation under the microscope. Unlike a biopsy where "chunks" of tissue are obtained, a fna often obtains only several drops of fluid that contain cells for evaluation.
