Definition
Oral cancer is a malignancy that occurs in different parts of the oral cavity, including: lips, the inside lining of the lips and cheeks (buccal mucosa), the teeth, the gums, the front two-thirds of the tongue, the floor of the mouth below the tongue, and the bony roof of the mouth (hard palate).
Characteristics
Epidemiology and Etiology
Oral cancer is a significant global health concern. It is responsible for over 300,000 new cases per year worldwide. Sixty to eighty percent of cases are diagnosed at a late stage (in high and low resource countries, respectively), resulting in poor five-year survival rates. Squamous cell carcinomas constitute more than 90% of malignant tumors of the oral cavity and oropharynx. Males shows a higher incidence than females, mainly because a significantly higher exposure to etiological factors. The main etiological factors are tobacco and alcohol use. These two agents are strongly...
