Fine needle aspiration biopsy (FNAB)

Fine-needle aspiration biopsy (FNAB) is a medical procedure used to diagnose abnormalities in tissues, such as lumps or growths. It involves using a thin, hollow needle to withdraw small samples of cells from the area of concern. This procedure is typically quick, minimally invasive, and can be done with local anesthesia. The extracted cells are then examined under a microscope to determine if they are cancerous or benign. FNAB is commonly used for assessing conditions in organs like the thyroid, breast, or lymph nodes, providing valuable information without the need for more invasive surgery.
