Abstract
Cancer is the second leading cause of death globally, making it a significant global health issue. Approximately half of cancer cases are linked solely to behavioral habits. Lifestyle changes made at a young age are easier to adopt and have lasting effects on future health, making early awareness about cancer essential. The "OncoAcademy: The Key to Health" project, aimed at high school Polish students, has been created to promote a positive health attitude and increase awareness among young people about cancer and methods of its prevention. From September 2023 to November 2024, we conducted educational sessions for 3000 high school students and assessed their cancer prevention knowledge before and after the project. Results revealed that students' level of knowledge before classes was moderate (M = 51.76%; SD = 13.63%). On average, students correctly answered 13 of 26 questions. After classes, the level of knowledge was assessed as moderately good (M = 62.47%; SD = 14.48%). On average, students correctly answered 16 out of 26 questions. The analysis revealed a statistically significant difference between the general level of knowledge-after classes, students achieved significantly better scores. This study highlighted changes in students' awareness and knowledge about cancer brought about by implementing a cancer education project. Generally, high school students in Poland have basic knowledge about cancer and its risk factors. Most adolescents are aware of the significant impact of lifestyle on cancer risk. Early education on cancer prevention, mainly aimed at lifestyle changes, is crucial. Enhancing adolescents' understanding of risk factors can play a significant role in lowering future cancer rates.
