Who gets head and neck cancers?
More than 5100 people in Australia are diagnosed with a head and neck cancer each year (excluding skin cancers). This includes about 1900 people with cancer in the mouth or tongue; 690 with lip cancer; 1300 with pharyngeal cancer; 570 with laryngeal cancer; 210 with nasal or paranasal sinus cancer; and 360 with salivary gland cancer.
Head and neck cancers are more common after the age of 40. Men are about three times more likely than women to develop a head and neck cancer, mainly because of men’s higher smoking and drinking rates (see below). Aboriginal and Torres Strait Islander people are more likely to develop head and neck cancer than other Australians.

What causes head and neck cancers?
The main factors that increase the risk of developing head and neck cancer are:
- smoking tobacco (including cigarettes, cigars and pipes)
- drinking alcohol
- infection with the human papillomavirus (HPV).
The combined effect of drinking and smoking is much greater than the risk of only drinking or only smoking. HPV is a very common infection that usually causes no symptoms.
Other risk factors account for only a small proportion of head and neck cancers. These risk factors include:
- having persistent sores or red or white patches in the mouth
- chewing tobacco, betel nut, areca nut, paan or gutka
- breathing in asbestos fibres, wood dust or certain chemicals
- poor dental health
- having a weakened immune system
- having had radiation therapy to the head or neck area in the past
- having too much sun exposure (for head and neck skin cancer)
- being overweight or obese
- having a parent, child or sibling with head and neck cancer (possibly because you have similar lifestyle factors)
- inheriting a condition linked to head and neck cancer (e.g. Fanconi anaemia, Li-Fraumeni syndrome).
Talk to your doctor if you are worried about any risk factors.
What is human papillomavirus (HPV)?
HPV is the name for a group of viruses that affect the surfaces or lining of different areas of the body, including the throat, cervix and skin. It is the most common sexually transmitted infection in humans. Most people don’t know that they have had an HPV infection.
The subtypes HPV 16 and HPV 18 are linked with throat cancer that starts in the tonsils and tongue base (oropharyngeal cancer). HPV in the head and neck area is usually spread through oral sex.
Most HPV infections are cleared by our immune system. In a small number of people, the virus can lie dormant for many years and then cause cancer. We still do not understand why this happens. HPV vaccination in adolescence can protect against HPV infection.
