Why Is This Important?

In New Jersey, 379 males and 323 females were diagnosed with brain and other nervous system (ONS) cancers during 2021. While a variety of risk factors have been found for brain and ONS cancers, the cause of most of these tumors is not fully understood.

Definition

Incidence rate of invasive brain and other nervous system cancers 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.

Data Notes

• Data have been age-adjusted to the U.S. 2000 standard population.
• Incidence rates (cases per 100,000 population per year) are age-adjusted to the 2000 US standard population (19 age groups: <1, 1-4, 5-9, ..., 80-84, 85+). Rates are for invasive cancer only (except for bladder cancer which is invasive and in situ) or unless otherwise specified. 2020 data are considered preliminary and should not be used in trend analyses; an approximate 10% decrease in the number of cancer cases diagnosed in 2020 and compared to 2019 is partly due to the COVID-19 pandemic. Patients experienced difficulties scheduling medical appointments and cancer screening tests in 2020. Incidence data for 2021 are considered preliminary due to possible reporting delays.

How the Measure is Calculated

• Numerator:

  Number of new cases of brain and other nervous system cancers among a defined population in a specified time interval.

• Denominator:

  Defined population in a specified time interval.
