As the name implies, head and neck cancer is a group of cancers that starts within the mouth, nose, throat, larynx, sinuses or salivary glands. Head and neck cancers combined are the sixth most common group of cancers in the world and oftentimes considered preventable because making certain lifestyle changes significantly lowers a person’s risk.
- An estimated 66,630 new cases of head and neck cancers will be diagnosed in the U.S. in 2021, with estimates of 14,620 deaths expected to result from the diagnosis.
- Head and neck cancers account for 4% of all cancers in the U.S.
- Men are two to three times more likely than women to develop a head or neck cancer because of their greater use of tobacco and alcohol. However, head and neck cancers found in women have been rising for several years.
- The consumption of tobacco (including cigarettes, cigars, pipes, and smokeless tobacco) and alcohol are the most common causes of head and neck cancers. Tobacco-induced head and neck cancer is slowly declining globally, in part to decreased use of tobacco.
- The fraction of head and neck cancers due to infection with the human papilloma virus (HPV) or Epstein-Barr virus HPV is rising. Other risk factors for head and neck cancers may include poor oral hygiene, exposure to occupational inhalants (such as asbestos or wood dust), a diet low in vegetables and fruits, gastroesophageal reflux disease, and a weakened immune system.
