About Head and Neck Cancer
Many people learn about head and neck cancer when they are diagnosed with it. You may wonder what it is, and how to take care yourself.
The term “head and neck cancer” refers to any cancer in that area, such as the nasal cavity, skin, sinuses, lips, mouth, salivary glands (uncommon), throat or larynx (voice box).
Head and neck cancers can also begin in the salivary glands, but salivary gland cancers are relatively uncommon. Salivary glands contain many different types of cells that can become cancerous, so there are many different types of salivary gland cancer.
Head and neck cancers account for approximately 3 percent of all cancers in the United States. These cancers are more common in men than women. Head and neck cancers are also diagnosed more often among people over age 50 than they are among younger people.
