DefinitionIncidence rate of leukemia by sub-type for a defined population in a specified time interval. Rates are age-adjusted to the 2000 U.S. Standard Population. Rates are per 100,000 population.
NumeratorNumber of new cases of leukemia by sub-type among a defined population in a specified time interval.
DenominatorDefined population in a specified time interval.
Why Is This Important?During 2015, 905 New Jersey males and 648 females of all ages were diagnosed with leukemias. At this time, we do not know what causes most leukemias.
How Are We Doing?The four most common types of leukemias occur with differing frequencies in adults versus children. Acute lymphocytic leukemia (ALL) is the most common type of childhood leukemia and also affects adults, especially those age 65 and older. Acute myeloid leukemia (AML) occurs in both adults and children. Chronic lymphocytic leukemia most commonly affects adults over age 55, and rarely occurs in children. Chronic myeloid leukemia (CML) occurs mainly in adults. Leukemia incidence rates and counts by age group are provided for the four most common types of leukemia. Detailed incidence rates and counts by gender and county are provided for the two most common types of leukemia (AML and CLL).
Although it is often thought of as a children's disease, most cases of leukemia occur in older adults. Leukemia is ten times more common in adults than in children, and more than half of all leukemia cases occur in people over the age of 65. The lifetime risk of developing leukemia is 1 in 56 for men and 1 in 79 for women.
What Is Being Done?A Comprehensive Cancer Control Plan was developed by the Task Force on Cancer Prevention, Early Detection and Treatment in New Jersey which aims to reduce the incidence, illness and death due to cancer among New Jersey residents. [https://www.cdc.gov/cancer/ncccp/ccc_plans.htm]
