DefinitionBrain and Central Nervous System (CNS) cancer incidence refers to the number of persons newly diagnosed with brain and CNS cancers within a specified time period and age group. Measures include 1) the number of newly diagnosed brain and CNS cancer cases; and 2) age-adjusted brain and CNS incidence rates (adjusted by the direct method to the 2000 US standard population). All rates are expressed per 100,000 persons.
NumeratorThe number of brain and CNS cancer cases newly diagnosed in New Mexico residents within a specified time period and age group. The data are based on the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program incidence site recodes for brain and CNS cancer: 31010-31040. http://seer.cancer.gov/siterecode/
DenominatorThe estimated population of New Mexico residents within a specified time period and age group.
Why Is This Important?Cancers of the brain and central nervous system (CNS) account for 1.4% of new cancer cases and nearly 3% of all cancer deaths in the U.S. This equates to 24,000 cases and 16,000 deaths. The five-year survival rate is 33.8%. Brain and spinal cancers are the second-most-common form of childhood cancer, accounting for 15% of cancer cases in children and adolescents.
Between 2010 and 2015, New Mexico has averaged about 120 new cases of brain and spinal cord cancer per year, with 14 of these annual cases occurring in children under the age of 20. These rates have remained relatively stable in New Mexico in recent decades.
The causes of brain and CNS cancer are not well understood, but appear to involve a combination of hereditary and environmental factors. Excess ionizing radiation exposure to the head is a known cause, but this accounts for very few cases.
