Recent trends have showcased a noticeable increase in the incidence of tongue cancer among Japan's younger population. Researchers are currently investigating the potential role that dental health, specifically crooked teeth, might play in this alarming trend. The study aims to uncover the possible link and subsequently devise prevention strategies.

Health management, particularly oral and dental health, are facets of lifestyle that are given due importance in Japan. Moreover, there's a prevalent societal focus on maintaining appearance, including straight teeth, thus, an issue like this garners significant attention. The rise in tongue cancer among young people and its speculated link to dental misalignment turns a potential aesthetic issue into a primary health concern, thereby stirring public interest and concern.

In the US or EU, there are also increasing trends in oral cancers among younger populations, although the focus has primarily been on the role of HPV rather than dental health. Similarly, dental health is a significant concern, as is cancer prevention, but the purported link between the two hasn't been as widely explored or discussed.
