WHO publishes childhood cancer survival data covering 194 countries
The World Health Organization announced on September 22, 2026, that a new international dataset on childhood cancer survival is now available through its Global Health Observatory.
The dataset provides comparable five-year survival estimates for children and adolescents with lymphoid leukaemia across 194 countries. It is intended to help health authorities identify differences in cancer outcomes and improve access to treatment.
What does the new WHO dataset show?
The figures use a common methodology to compare childhood leukaemia survival across WHO Member States.
According to WHO, five-year survival estimates in high-income countries reach approximately 80–90%, while countries with weaker healthcare systems may have rates closer to 40%.
The findings highlight substantial differences in access to early diagnosis, essential medicines and specialist cancer care.
Why are the figures important?
Approximately 400,000 children and adolescents develop cancer worldwide each year, according to WHO estimates.
The newly available data provide a standardized basis for comparing countries and monitoring improvements in childhood cancer care.
However, the published survival estimates specifically concern lymphoid leukaemia and should not be interpreted as survival rates for every type of childhood cancer.
What happens next?
WHO aims to increase global childhood cancer survival to at least 60% by 2030.
Governments and healthcare organizations can use the dataset to identify gaps in diagnosis and treatment and assess progress toward this target.
The underlying report was published in May 2026. The new development announced on September 22 is the availability of its country-comparable dataset through WHO's online data portal.
