WHO & International Childhood Cancer Day

Dr Oleg Chestnov, Assistant Director-General for Noncommunicable Diseases and Mental Health at the World Health Organization notes "Every child has the right to quality cancer treatment and services, regardless of geography or financial situation." He underscores that "the majority of children with potentially curable cancers can get cured even in low-resource settings, and all children with advanced cancer can benefit from pain relief and palliative care wherever they live. Children’s rights cannot be fulfilled and protected unless preventing and treating cancers is included as a priority within national cancer control programs."
