Five sub-districts were selected from each of the three sub-districts, withseven participants sampled from 10 sub-districts and six participants sampled fromfive sub-districts. Participants were selected using purposive sampling. The programemployed a participatory research approach based on community empowerment,using the TPS (Transactional, Precise, and Skilled) communication model. The programwas conducted in three stages. In the first stage, theoretical information relatedto breast cancer and its prevention was provided, along with 100 questions andanswers shared online beforehand. The second stage involved practicing breast selfexamination(SADARI). The third stage combined theory and practice, incorporatingeducational strategies through games and evaluations. The program results showedthat 83% of participants agreed that knowledge about breast cancer and its preventionwas necessary. The program successfully improved the knowledge and attitudes ofPKK/health cadres through an interactive, participatory approach. Although therewere barriers related to participant agility, support from trained organizers provedeffective in overcoming them.
