What causes cancers of the head and neck and who’s at risk?
According to a recent review of studies, 73% of head and neck cancers in the United States are associated with human papillomavirus (HPV) infection. This infection is transmitted between people through sexual contact. It’s important to note that most people with HPV do not know they have it because it rarely causes symptoms.
Both men and women can develop head and neck cancers associated with an HPV infection. Although HPV can be detected in different head and neck cancers, it only causes oropharyngeal cancers.
The other two main causes of head and neck cancers are alcohol and tobacco.
Some additional risk factors include:
- Chewing betel quid (popular in South Asia, Southeast Asia, and the Pacific islands)
- having the Epstein-Barr virus
- being male
- being older than 40 years
- experiencing occupational exposure to wood dust, asbestos, and other substances
