Breast cancer is one of the serious health problems worldwide, including in Indonesia. Breast health education plays an important role in increasing public awareness of the dangers of breast cancer, including in adolescents. The purpose of this study was to determine the effect of breast health education as an early detection system on attitudes about breast cancer prevention in grade VII students. This study design used a pre-experimental with a one group pre-test-post test design. The sample of this study was 51 students using a purposive sampling technique. Data were collected using an attitude questionnaire. Data analysis used the Wilcoxon Test with a significance level of 0.05. The results of the study showed that before being given education, 47 respondents (92%) had good attitudes, while a small portion of 4 respondents (8%) had bad attitudes. And after being given education, 42 (96%) respondents had good attitudes and a small portion (4%) 2 respondents had bad attitudes. The results of the data analysis p 0.000 0.05 then H1 is accepted, meaning that there is an effect of education on improving the attitudes of grade VII students. The results of the study showed that health education greatly influenced students' understanding and attitudes about breast cancer prevention by routinely performing BSE once a month after menstruation. In addition to health education, support from the surrounding environment starting from parents, health workers and peers also influenced understanding of attitudes about breast cancer prevention.

Adolescents need to know the main action to be given to OHCA (out-of-hospital cardiac arrest) patients because people who were close to cardiac arrest patients have an essential role in performing the resuscitation. The rapid resuscitation in the first few minutes will increase the chance of survival by double to triple. Increasing the ability of nonexpert people to perform resuscitation can be performed by providing training using standardized American Heart Association resuscitation videos. The study aimed to determine the change in resuscitation attitudes among adolescents after receiving the training video. The quasi-experimental design was used within a pretest-posttest group. The population of this study was 160 adolescents, and 94 respondents were recruited using a purposive sampling technique according to the inclusion criteria for high school youth who had never received cardiopulmonary resuscitation (CPR) training inside or outside of school. The variables in this study were training videos and attitudes to the practice. Data were analyzed using the Wilcoxon test. The results showed the attitudinal variable (p=0.0000.05). Among 94 respondents whole had a positive attitude (100%) before and after receiving the CPR training video. The attitudes are increasing after the implementation of the CPR training video compared to before the intervention. Providing first aid training to help cardiac arrest patients using training videos to the adolescent by healthcare team needs to be increased.
