Of all Cancers, Oral cancer is one of the most typical cancers in the world. Oral cancer has delayed clinical detection, poor prognosis, without specific biomarkers, and expensive therapeutic methods. This study aims to explain the basic aspects of oral cancers and focuses on squamous cell carcinoma of the oral cavity. The duration of cancer detection depends on the amount and duration of tobacco usage of the individual. In this study, we have presented stochastic models for squamous cell carcinoma onset and progression of oral cancer-affected individuals.
