Researchers have studied childhood cancers for many years but still do not know a lot about what causes them. Finding the causes of childhood cancers is challenging because cancer in children is rare and each type of cancer may have different factors that lead to its development. It's difficult to identify environmental factors related to childhood cancer because environmental exposures to the parent, the child in the womb, or the child after birth may play a role. Data for the following Childhood Cancers are available:
- Childhood Brain and Nervous System Cancer
- Childhood Leukemia
- Childhood acute lymphocytic leukemia
- Childhood acute myeloid leukemia
Annual Children Under 15 Cancer Incidence Data
Annual cancer incidence measures can be used to identify trends and patterns of cancer incidence over time. Annual measures are only available at the state level.
Measure Description:
- The Under 15 Case Count is the number of newly diagnosed malignant cancers among children under the age of 15.
- The Under 15 Age Adjusted Rate (Per 1,000K) is the age adjusted rate of newly diagnosed malignant cancers among children under the age of 15 per 1,000,000 population under the age of 15. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
Annual Children Under 20 Cancer Incidence Data
Annual cancer incidence measures can be used to identify trends and patterns of cancer incidence over time. Annual measures are only available at the state level.
Measure Description:
- The Under 20 Case Count is the number of newly diagnosed malignant cancers among children under the age of 20.
- The Under 20 Age Adjusted Rate (Per 1,000K) is the age adjusted rate of newly diagnosed malignant cancers among children under the age of 20 per 1,000,000 population under the age of 20. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
