Interventions
BEHAVIORALWhatsApp-Based Cancer Prevention Messaging

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.
