Fine Needle Biopsy SoCal’s Otolaryngology Experts
A fine needle biopsy (FNB) is a minimally invasive procedure used to collect tissue or fluid samples from suspicious lumps, nodules, or enlarged lymph nodes. This quick and effective test helps diagnose benign or malignant conditions, including thyroid nodules, swollen lymph nodes, and salivary gland abnormalities.
