Epidemiology is the study of the distribution and determinants of disease frequency in the human population and the study to control health problems. Cancer is the second leading cause of death in males and fourth in women under the age of 20 in the United States. The survival rate of children with cancer has improved since the late 1960s which is due to improved treatment and public health measures. The estimated proportion surviving 5 years from diagnosis increased from 77.8 percent to 82.7 percent to 85.4 percent for those diagnosed in the 1990s, 2000s, and 2010–2016, respectively.

Epidemiology is the study of the distribution and determinants of disease frequency in the human population and the study to control health problems. Cancer is the second leading cause of death in males and fourth in women under the age of 20 in the United States. The survival rate of children with cancer has improved since the late 1960s which is due to improved treatment and public health measures. The estimated proportion surviving 5 years from diagnosis increased from 77.8 percent to 82.7 percent to 85.4 percent for those diagnosed in the 1990s, 2000s, and 2010–2016. Non-Hispanic white children often have a better chance of survival compared to other racial and ethnic groups. Where an individual lives is one of the biggest determents of health in the world as illness can vary by an individual's zip code.

Sub-Saharan Africa

A large number of children in Africa live in low to middle-income countries throughout Africa where there is limited access to prevention or treatment of cancer. The under-five-mortality rate (U5MR), a robust indicator of child health, is at 109 per 1,000 live births. The proportion of childhood cancer is higher in Africa than in developed countries at 4.8%. Kids with cancer are disadvantaged compared to kids in developed countries therefore their statistic for childhood cancer is higher. In sub-Saharan Africa, 10% of children die before their 5th birthday, yet it's not due to cancer but communicable diseases are the leading cause of death. Children with cancer are often exposed to these preventable infections and diseases. Tumor registries only cover 11% of the African population and there is a significant absence in death registration making the mortality database unreliable. Overall, there is a lack of reliable data as there is limited funding and many diseases are largely unknown to this population.
