Cancer care in conflict-affected regions: a scoping review of service delivery challenges, healthcare system adaptations, and policy implications

BACKGROUND: Armed conflicts severely disrupt cancer care delivery, destroying infrastructure and limiting access to essential diagnostics and treatments. Evidence on service challenges, adaptations, and policy implications remains fragmented. METHODS: This scoping review of four databases (Scopus, PubMed, ScienceDirect, and CINAHL) was conducted for original peer-reviewed studies published between January 2020 and August 2025. The search focused on the effect of wars on cancer service delivery in conflict zones, and its impact on cancer care. RESULTS: Wars in conflict-affected countries like Palestine, Sudan, Syria, Iraq, Ukraine, and Afghanistan caused widespread destruction of cancer infrastructure, unsafe hospitals, and interruptions in chemotherapy, radiotherapy, and surgery. Countries faced shortages of specialized centers, technicians/radiologists, and medical records, alongside high costs and supply chain disruptions. Despite these challenges, healthcare systems demonstrated resilience through adaptations including Ukraine's MedEvac program for EU treatment evacuation, cross-border referrals (Iraq→Lebanon, Afghanistan→Pakistan), telemedicine, mobile diagnostic units, and community-based care models. Policy responses emphasized international aid coordination, conflict-sensitive health planning, and supply chain restoration. CONCLUSION: Conflicts cause infrastructure destruction, workforce depletion/migration, treatment barriers/delays, drug supply disruptions, and psychosocial/economic impacts, which in turn create urgent policy/governance challenges. Although humanitarian aid may provide temporary relief, sustainable solutions require peace and global commitment, grounded in equity and the fundamental right to health.
