There are approximately 21,000 new cases of oral cancer every year. Although the oral cavity is relatively accessible to examination, malignant processes tend to present late with poor prognosis. To improve tumor outcome, early detection and treatment is essential. This article reviews the realms of oral cancer and its causes, as well as early detection methods and screening technologies that may be used. Currently available screening tools may help in visualizing an existing lesion or its borders, but they add little in discriminating between a premalignant, malignant, or inflammatory process.
