Fine-needle aspiration is a method of collecting cells from the breast, liver, mouth, neck, lymph nodes, genitals, respiratory tract, or thyroid to look for signs of cancer, infection, or other conditions. During a fine-needle aspiration, a health professional inserts a thin needle into a suspicious lump and removes cells that are then examined under a microscope.
