“…However, in some cases, no classical risk factors are present at OSCC diagnosis (de Souza et al, 2020; Monção et al, 2020). Although specific clinical characteristics have been identified (de Carvalho Fraga et al, 2014; Fonseca‐Silva et al, 2012; Santos et al, 2021), including lifestyle and human papillomavirus (HPV) status (Fonseca‐Silva et al, 2012; Marques‐Silva et al, 2012), it remains unclear what exactly initiates carcinogenesis or what facilitates intrinsic carcinogenesis, also known as non‐habit‐related carcinogenesis (de Souza et al, 2020b; Monção et al, 2020). Some studies have reported that, generally, these cases are clinically more complex to treat, raising the hypothesis that this type of cancer develops through different routes of carcinogenesis (de Carvalho Fraga et al, 2014; De Paula et al, 2009; de Souza et al, 2020a; Farias et al, 2010; Fraga et al, 2012; Marques‐Silva et al, 2012; Santos et al, 2021).…”
