Mean age at diagnosis increased for three of the four HNC evaluated. Oropharyngeal cancer was the only subsite to demonstrate an overall proportional increase, mainly in middle age (40-59 years) patients. Cancers of the oral cavity were the only subset to show a true increase in the proportion of young (0-39 years) patients. When stratifying by gender, the proportion of young patients in female HNC cases is higher than the proportion of young male HNC cases.
