Prevention, early detection, and treatment of oral cancer
The major causes of oral cancer include tobacco use, areca nut chewing and heavy alcohol
drinking; avoiding these can prevent the disease. Preceded by precancerous lesions, early oral
cancers present as small painless ulcers or growths that can be detected, by careful physical
examination, and effectively treated. Prevention, early detection and treatment are effective
interventions to reduce the worldwide burden of oral cancer.
