Fine needle aspiration (FNA) biopsy

Fine needle aspiration (FNA) biopsy is a minimally invasive procedure used to collect cells from a lump or mass, often to check for disease such as cancer. A thin, hollow needle is inserted into the area of concern, guided by imaging like ultrasound. Suction is gently applied to draw cells into the needle, which are then examined under a microscope. This method allows for quick, accurate sampling with minimal discomfort and no major surgery, helping doctors diagnose conditions effectively.
