BSE practice is a breast examination performed by women to detect breast cancer lumps. This disease occupies the highest percentage of cases of other cancers and the highest percentage of deaths in women in the world. Breast cancer can be detected by prevention, one of which is breast self-examination (BSE). The tendency of women in early breast cancer detection with BSE is still low, even in 2015 non-health faculty students at the University of Jember. Many studies state that non-health faculty students are mostly rare and never practice BSE. This study aims to analyze the relationship of knowledge, attitudes, sources of information, peer support and anxiety about BSE practices in 2015 college students at the University of Jember. This type of study is analytic with cross sectional approach. The study was conducted on 227 respondents. The sampling technique is proportional random sampling. The results showed that there was a correlation between knowledge, attitudes, sources of information, peer support and the level of anxiety about BSE practices. After the logistic regression test, it showed that the knowledge most related to BSE practice was p-value 0.083. Keywords: Breast cancer, non-health faculty students, BSE practice
