Testicular cancer represents the most common form of cancer among young men in many parts of the world. Its specific distribution among young individuals makes it not only a medical challenge but also a social issue that requires early detection, accurate diagnosis, and appropriate treatment to increase survival rates and improve the quality of life for those affected. One of the key preventive strategies is testicular self-examination, a simple, non-invasive, and accessible way to monitor one's own health. This master's thesis explores the level of knowledge and attitudes of University North students about testicular cancer and testicular self-examination. The research objectives include examining the level of knowledge and attitudes of students, as well as analyzing potential statistically significant differences in knowledge and the practice of testicular self-examination based on age, place of residence, educational level, and field of study. The research methodology involves conducting a survey among University of North students. The results of the study indicate a variable level of knowledge among students, with those in the biomedical and healthcare field exhibiting a higher level of knowledge about testicular cancer compared to students from other study programs. Additionally, students with a graduate degree demonstrated a higher level of knowledge than those with a high school or undergraduate education. The study identified deficiencies in recognizing testicular cancer as a common disease among young people, highlighting the need to increase awareness on this topic. Awareness regarding testicular self-examination also requires additional attention and education, given the low rate of practice among students. This work contributes to understanding the knowledge and attitudes of students about testicular cancer and identifies areas that require further education and awareness. It also emphasizes the importance of the role of nurses as healthcare professionals in educating and implementing preventive programs aimed at different groups of men to improve testicular cancer prevention and the health of young men.
