Oral cancer refers to cancers that develop on the tongue, oral mucosa (tissue lining the mouth and gums), and on the floor of the mouth. There are several types of oral lesions that have the potential to become cancerous. These include white lesions (leukoplakia), the most commonly diagnosed precancerous lesions in the mouth, and red, velvet-like lesions (erythroplakia). Of those lesions that become cancerous, about 90 percent are a type of tumor called squamous cell carcinoma.
