Head & Neck Cancer is a term used to describe a number of different malignant tumors that develop in or around the throat, larynx, nose, sinuses, and mouth.
Most head and neck cancers are squamous cell carcinomas, meaning they begin in the flat, squamous cells that make up the thin surface layer of the structures in the head and neck. Directly beneath this lining, which is called the epithelium, some surrounding areas have a layer of moist tissue, called the mucosa. If a cancer is limited to the squamous layer of cells, it is called carcinoma in situ. If the cancer has grown beyond this cell layer and moved into the deeper tissue, then it is referred to as invasive squamous cell carcinoma.
There are five main types of cancer, each named according to the part of the body where they develop. For more information, including signs and symptoms about each different form of cancer that forms in the head and neck are listed below.
Laryngeal and Hypopharyngeal Cancer. The larynx is commonly called the voice box. It is a tube-shaped organ in the neck that is important for breathing, talking, and swallowing. It is located at the top of the windpipe, or trachea. The hypopharynx is also called the gullet. It is the lower part of the throat that surrounds the larynx.
Nasal Cavity and Paranasal Sinus Cancer. The nasal cavity is the space just behind the nose where air passes on the way to the throat. The paranasal sinuses are the air-filled areas that surround the nasal cavity.
Nasopharyngeal Cancer. The nasopharynx is the air passageway at the upper part of the throat behind the nose.
Oral and Oropharyngeal Cancer. The oral cavity includes the mouth and tongue. The oropharynx includes the middle of the throat from the tonsils to the tip of the voice box.
Salivary Gland Cancer. The salivary gland is tissue that produces saliva, which is the fluid that is released into the mouth to keep it moist and that contains enzymes that begin breaking down food.

What Are Laryngeal and Hypopharyngeal Cancers?
Laryngeal and Hypopharyngeal cancer are the most common types reported in the U.S. The malignant tumors grow and produce squamous cells that form a lining in the lower part of the throat. Laryngeal cancer occurs when cancer cells form in the tissue above the trachea. It can impact one’s ability to breathe, swallow, and talk. Hypopharynx, on the other hand, is in the lower part of the throat. This organ surrounds the larynx. According to the American Cancer Society (ACS), statistics indicate that laryngeal cancer is more common than hypopharyngeal cancer.
