Introduction: Cancer-related pain remains a major public health challenge in Latin America, where systemic, professional and social barriers frequently delay access to adequate palliative care.

Methods: The Palliative Care Council of the Argentine Society of Medicine organised the National Week Against Cancer Pain 2025, the second edition of a nationwide initiative first launched in 2022. The programme combined digital advocacy, community-based educational activities and a volunteer‑led clinical network. Mass-media communication was amplified by public figures, alongside in‑person and virtual activities for the community and free clinical consultations delivered through a dedicated web platform supported by institutional digital channels.

Results: During the peak activation period, the campaign achieved nearly 50,000 direct digital impressions, with substantial additional reach generated through secondary dissemination by high‑profile influencers. More than 100 free clinical consultations were provided, both virtually and in person, across 13 Argentine provinces. Community‑based activities were conducted in multiple regions, supported by academic societies, provincial governments and civil organisations. The initiative generated over 50 appearances in national and regional media outlets.

Conclusion: A coordinated strategy combining digital innovation, community engagement and professional volunteerism can significantly reduce barriers to cancer pain management. This experience offers a scalable and replicable model for improving early access to palliative care in middle‑income countries.
