What is Head & Neck Cancer?

Head and Neck Cancer includes different types of cancer that can develop in the mouth, nose and throat. Head and Neck tumors are made up of different types of cells. Most types of Head and Neck Cancer are considered squamous cell carcinomas of the head and neck (SCCHN), while some are considered adenocarcinoma.

Pharynx: The pharynx is located between the esophagus and the mouth. Cancer of the pharynx can occur in any of the pharynx’s three parts:

Oral Cavity: Cancer of the oral cavity occurs in the lips, gums, lining of the lips and cheeks, bony top of the mouth, small area behind wisdom teeth, front part of the tongue, or underneath the tongue.

Salivary Glands: Cancer of the salivary glands occurs mostly in the bottom of the mouth, near the jawbone.

Paranasal Sinuses and Nasal Cavity: Cancer of the paranasal sinuses and nasal cavity occur in the sinuses around the nose or the nasal cavity.

Larynx: The larynx, or voice box, is the short pathway below the pharynx in the neck and includes the vocal cords and epiglottis. Lymph Nodes in the Upper Neck: Sometimes head and neck cancer is found exclusively in the lymph nodes in the upper neck. This type of cancer is known as locally advanced incarcinoma with unknown origin.
