"Staging"
"As they share epidemiology, pathology and general principles with other squamous cell carcinomas of the upper aerodigestive tract, those topics are covered there. Below are a few general comments specific to the oral cavity. Imaging findings, treatment, and prognosis are sometimes subsite-specific and are therefore in some cases discussed separately:"
"A common staging system is used for all squamous cell carcinomas of the oral cavity, with tumour staging being based on size and extension into adjacent structures. Nodal staging is the same as that used for squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx and larynx (see: staging of oral cavity squamous cell carcinomas)."
