Globally, head and neck cancer accounts for 650,000 new cases of cancer and 330,000 deaths annually on average. In 2018, it was the seventh most common cancer worldwide with 890,000 new cases documented and 450,000 dying from the disease. In the United States, head and neck cancer makes up 3% of all cancer cases (averaging 53,000 new diagnoses per year) and 1.5% of cancer deaths Notably, head and neck cancer secondary to chronic alcohol or tobacco use has been steadily declining as less of the population chronically smokes tobacco. However, HPV-associated oropharyngeal cancer is rising, particularly in younger people in westernized nations, which is thought to be reflective of changes in oral sexual practices.
