Survival rates for most childhood cancers have improved in recent decades and improvement has been especially dramatic for a few types from 1975 to 2012:

• For acute lymphoblastic leukemia, the most common childhood cancer, the five-year survival rate rose from 57% to 92%.

• For non-Hodgkin lymphoma, the five-year survival rate increased from 43% to 91%.

Some other key stats include:

• 10,500: Estimated number of children under the age of 15 who will be diagnosed with cancer in 2021.

• 84%: The percentage of children diagnosed with cancer who will survive at least five years.

• The number of cancer deaths for people under 20 was 5.1 per 100,000 children in 1975.

• The number of cancer deaths for people under 20 was 2.2 per 100,000 children in 2017.
