This specialty focuses on diagnosing diseases of the head and neck region, including the mouth, nose, throat, sinuses, salivary glands, and larynx. Pathologists in this field play a vital role in diagnosing a wide range of benign and malignant conditions, such as head and neck cancers (squamous cell carcinoma), infections, and inflammatory diseases. They evaluate biopsy specimens from the oral cavity, pharynx, or thyroid gland and help guide the selection of treatment options, such as surgery or radiation therapy.
