ABSTRACT
The oral cavity is a part of the upper aerodigestive tract that begins at the lips and ends at the anterior surface of the faucial arch. Oral cancer is an umbrella term that consists of cancers that originate in the oral tissues. The primary site of origin of oral cancers is submucous tissues, the epithelium, and minor salivary gland. Some of the other common subsites of oral carcinoma are the alveolus, tongue, buccal mucosa, and gingivobuccal sulcus.
