FNAC stands for Fine Needle Aspiration Cytology. It is a medical procedure that involves using a fine needle to extract cells from a lump or tumor, usually found in the breast, thyroid, lymph nodes, or other parts of the body. The extracted cells are then examined under a microscope to determine if they are cancerous or benign. FNAC is a minimally invasive procedure that helps in the diagnosis of various diseases, especially cancer.
