Oral cancer: etiology, precancerous lesions and treatment: A literature review

Introduction: Oral cancer is one of the most common malign neoplasia around the world. However, despite current diagnosis tools, a high morbidity and mortality rate is present due to a late diagnosis and a lack of population consciousness about tobacco, alcohol, and other substances consumption. Objective: The current review aims to provide updated information about precancerous lesions, etiology, diagnosis, and treatment of oral cancer. Methodology: A bibliographic research on peer review articles were done in five digital repositories considering publications from 2015 up to date. Conclusion: Oral cancer is a frequent pathology with severe consequences for its affected patients. A wide knowledge on pre-malign lesions, risk factors, and early diagnosis is key to prevent the presence and development of this pathology.
