In England, oral cancer rates, including cancers of the oral cavity and oropharynx, have increased by more than 130% since 2000, with mortality also steadily rising [1] . Accumulating evidence suggests that Asian/Asian British ethnic groups and socioeconomically deprived groups are at highest risk. Among Asian/ Asian British individuals, the incidence of OCC is 6.27 per 100,000, compared to 5.96 per 100,000 in White individuals. However, data is limited due to a lack of robust ethnicity data coding and recording [1, 2] . The variation by socioeconomic status is stark with a standardised incidence of 11.13 per 100 000 in the most deprived quintile compared to 6.68 per 100 000 in the least deprived [2] . The drivers of this increased risk are likely to be multifactorial encompassing not only inequities in access to healthcare services but also differences in knowledge, health behaviours and lifestyle risk factors. Biological determinants of disease may also play a role.  \nThe majority of oral cavity cancers are squamous cell carcinomas and the aetiology is strongly linked to risk factors including alcohol consumption and use of tobacco [2]. Alarmingly, around half of oral cavity cancers are diagnosed as Stage IV necessitating more complex and multimodal treatment, with in some situations, palliative treatment being the only option [2] .  \nWe recently reported worse disease outcomes in South Asian individuals, defined as self-reporting as Indian, Pakistani and Bangladeshi, receiving radiotherapy for oral cavity cancers in a single centre serving a super-diverse community [3] . We found poorer 2-year disease-free survival in South Asian individuals compared to non-South Asian individuals, 54.6% vs. 73% respectively, even when adjusted for deprivation. Additionally, locoregional recurrence was more frequent in South Asian individuals compared to non-South Asian individuals, 42.5% vs  \n22.1% respectively, despite similar disease characteristics [3] . A similar study in Canada, also highlighted poorer outcomes in East Indian patients with OCC [4] . It is unknown whether ethnicity, independently, determines patient outcomes or whether there exists an interplay of socioeconomic, cultural and behavioural factors. Variations in genetic, biological and environmental factors between individuals may influence disease trajectory and treatment adherence, tolerability and resultant disease outcome [5] . This has not been fully explored within different ethnic groups.  \nIn the United Kingdom, although smoking remains the most common form of tobacco use across all communities, smokeless tobacco products, whose composition varies significantly, are most commonly used by South Asian individuals, particularly those of Bangladeshi origin [6] . Recreational use of smokeless tobacco and betel nut is strongly linked with variation in the incidence of, and mortality from, oral cavity cancers globally with the highest rates in South-East Asia as well as in South Asian populations in the UK, particularly Indo-Asian immigrants[7","cbCairW0a4vQYNuf","https://ap.wps.com/l/cbCairW0a4vQYNuf","pdf",279533,"English","# Epidemiology\n## Rising incidence and risk patterns\n## Stage at diagnosis and treatment complexity\n## Evidence on ethnic disparities in outcomes\n## Potential drivers and healthcare inequities\n## Public health and service access priorities","[{\"question\":\"Which UK groups face the highest risk for oral cavity cancer?\",\"answer\":\"Asian/Asian British ethnic groups and socioeconomically deprived groups show the highest risk in the UK.
