Types of head and neck cancers

Head and neck cancers are usually categorised by the area of the head and neck region that the cancer starts. These areas include:^1,2

• Mouth (oral cavity) – including the lips, tongue, gums, and other structures inside the oral cavity
• Throat (pharynx)
• Voice box (larynx)
• Nose – including the nasal cavity and sinuses
• Salivary glands
• Skin of the head and neck

There are three main types of head and neck cancer, which are named after the type of cell that the cancer starts in:^1,2

• Mucosal squamous cell carcinomas start in the squamous cells, or moist lining, of the mouth, nose, and throat, and account for around 9 in 10 head and neck cancers*
• Adenocarcinomas start in the glandular cells of the head and neck area
• Cutaneous carcinomas start in the skin of the head and neck area

Head and neck cancers can be associated with a number of different symptoms, which are usually specific to the type and location of the cancer. However, some general symptoms may include:^1,2

Radiation therapy - Radiation therapy uses a controlled dose of radiation, usually in the form of x-rays, to destroy or damage the cancer cells. Radiation therapy may be used as the main treatment for head and neck cancer or used together with other treatments to treat the cancer or help relieve symptoms.¹

Chemotherapy - Chemotherapy uses medications, usually given by injection or tablet, to help kill cancer cells or slow their growth and spread. Chemotherapy can be used in conjunction with other cancer treatments.¹
