Early changes
Carcinoma of the lip usually follows erythroleukoplakia, or it can be asymptomatic at first. In these cases, it looks like a thick, blistering patch that looks whitish or pigmented. Carcinoma of the tongue often starts feeling as superficial glossitis (inflammation of the tongue), or looks like leukoplakia. The carcinoma and adenocarcinoma of the hard palate start as an irregular mass, which may ulcerate later with rolled out edges.
