This nation-wide study showed a significant rise in incidence of HNC for men and women along with a significant increase in relative survival. Oropharyngeal cancer had the highest increase in incidence followed by hypopharyngeal cancer which showed the poorest survival of HNCs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
