Participants in this group will receive a structured series of WhatsApp messages containing evidence-based cancer prevention recommendations from the Latin America and Caribbean Code Against Cancer (LAC Code). Messages will be delivered over four weeks, 3 times a week, covering key topics such as smoking cessation, healthy diet, physical activity, and regular screening. Engagement metrics will be tracked to assess feasibility and adherence.
Healthcare professionals assigned to this group will participate in an online workshop designed to improve their knowledge of the LAC Code and communication strategies for cancer prevention counseling. The workshop includes recorded lectures, interactive modules, and knowledge assessments. Completion rates and participant satisfaction will be measured.
