Oral cancer 1 article

Oral cancer refers to malignant disease arising in tissues of the oral cavity, most commonly squamous cell carcinoma of the mucosal epithelium. Persistent ulcers, masses, induration, unexplained red or white lesions and other changes may prompt urgent assessment, but diagnosis requires appropriate clinical evaluation and usually tissue biopsy. Tobacco, alcohol and other risk factors influence risk in different populations. The term denotes malignant oral disease rather than every suspicious lesion or screening finding.
