Head and Neck Cancer
Description
Most head and neck cancers begin in the cells that line the mucosal surfaces in the head and neck area, i.e., mouth, nose and throat.
Cancers of the head and neck are further identified by the area in which they begin. Oral cavity. The oral cavity includes the lips, the front two-thirds of the tongue, the gingiva (gums), the buccal mucosa (lining inside the cheeks and lips), the floor (bottom) of the mouth under the tongue, the hard palate (bony top of the mouth) and the small area behind the wisdom teeth.
Head and neck cancer types include:
- Salivary glands. The salivary glands produce saliva, the fluid that keeps mucosal surfaces in the mouth and throat moist. There are many salivary glands; the major ones are in the floor of the mouth and near the jawbone.
- Paranasal sinuses and nasal cavity. The paranasal sinuses are small hollow spaces in the bones of the head surrounding the nose. The nasal cavity is the hollow space inside the nose.
- Pharynx. The pharynx is a hollow tube about 5 inches long that starts behind the nose and leads to the esophagus (the tube that goes to the stomach) and the trachea (the tube that goes to the lungs). The pharynx has three parts: Nasopharynx. The nasopharynx, the upper part of the pharynx, is behind the nose. Oropharynx. The oropharynx is the middle part of the pharynx. The oropharynx includes the soft palate (the back of the mouth), the base of the tongue, and the tonsils. Hypopharynx. The hypopharynx is the lower part of the pharynx.
- Larynx. The larynx, also called the voicebox, is a short passageway formed by cartilage just below the pharynx in the neck. The larynx contains the vocal cords. It also has a small piece of tissue, called the epiglottis, which moves to cover the larynx to prevent food from entering the air passages.
Symptoms
Symptoms of several head and neck cancer sites include a lump or sore that does not heal, a sore throat that does not go away, difficulty swallowing and a change or hoarseness in the voice. Other symptoms may include the following:
- Oral cavity. A white or red patch on the gums, tongue or lining of the mouth; a swelling of the jaw that causes dentures to fit poorly or become uncomfortable; and unusual bleeding or pain in the mouth.
- Nasal cavity and sinuses. Sinuses that are blocked and do not clear, chronic sinus infections that do not respond to treatment with antibiotics, bleeding through the nose, frequent headaches, swelling or other trouble with the eyes, pain in the upper teeth or problems with dentures.
- Salivary glands. Swelling under the chin or around the jawbone; numbness or paralysis of the muscles in the face; or pain that does not go away in the face, chin or neck.
- Oropharynx and hypopharynx. Ear pain.
- Nasopharynx. Trouble breathing or speaking, frequent headaches, pain or ringing in the ears or trouble hearing.
- Larynx. Pain when swallowing or ear pain.
- Metastatic squamous neck cancer. Pain in the neck or throat that does not go away.
Common Treatment Options
Head and neck cancers typically may be treated with chemotherapy, radiation therapy, immunotherapy (the use of anticancer drugs combined with biologic therapy to boost the immune system to kill cancer cells), vaccine therapy (helping the immune system recognize and attack specific types of cancer cells) or surgery.
