Head and neck squamous cell cancer (HNSCC) is a type of squamous cell cancer found in the outer layer of skin and mucous membrane. HNSCC is classified by its occurrence site, such as the oral cavity, larynx, hypopharynx, as well as nasal cavity. Common symptoms of HNSCC include ulcers in the throat, abnormal bleeding in the mouth, unclear sinus congestion, sore throat, sore ears, pain and difficulty swallowing, hoarseness, or swollen lymph nodes. HNSCC can spread to other human body parts and has a worse prognosis. About 50% of patients with HNSCC survive only 3-5 years after diagnosis.
