The inside of the mouth is normally lined with a special type of skin (mucosa) that is smooth and coral pink in color. Any alteration in this appearance could be a warning sign for a pathological process. The most serious of these is oral cancer. The following can be signs at the beginning of a pathologic process or cancerous growth:
Reddish patches (erythroplasia) or whitish patches (leukoplakia) in the mouth.
A sore that fails to heal and bleeds easily.
A lump or thickening on the skin lining the inside of the mouth.
Chronic sore throat or hoarseness. Difficulty in chewing or swallowing.
