RESUMEN
Introduction: The expansion of knowledge about head and neck cancer can provide greater care and the ability to identify risk factors and symptoms of the disease, as well as the incorporation of healthy habits. The younger these concepts are sedimented, the better results will be, making society healthier and more aware. Objective: To assess knowledge about head and neck cancer among adolescents from private schools, aged between 13 and 22 years. Methods: 200 questionnaires were applied among students, about the profile of adolescents and their knowledge about head and neck neoplasms, treatment, and teaching in schools on this topic. The results were analyzed both quantitatively and qualitatively. Results: Only 55 students (29.9%) identified HPV as a risk factor for the disease. 137 students (74.5%) identified the brain as an organ treated by head and neck surgery. As for the therapeutic strategies used for the treatment of neoplasms in the region, only 67 students (36.4%) are aware. On the topic of teaching in schools, 153 students (83.1%) relate to some deficiency in the approach and learning. Conclusion: Knowledge about head and neck cancer is insufficient. It is necessary to introduce in the curriculum basic cancer education in biology classes. The expansion of acquirements about cancer can provide better care and the ability to identify risk factors, initial signs, and symptoms of the disease, as well as the incorporation of healthy habits in families because these students can propagate valid information in their environment.
