Notes:
Created by statecancerprofiles.cancer.gov on 04/25/2025 10:04 pm.
State Cancer Registries may provide more current or more local data.
Data cannot be shown for the following areas. For more information on what areas are suppressed or not available, please refer to the table.
Baca, Bent, Cheyenne, Conejos, Costilla, Crowley, Custer, Dolores, Gilpin, Hinsdale, Huerfano, Jackson, Kiowa, Lincoln, Mineral, Ouray, Phillips, Saguache, San Juan, Sedgwick, Washington
† 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. Rates calculated using SEER*Stat. Population counts for denominators are based on Census populations as modified by NCI. The US Population Data File is used for SEER and NPCR incidence rates.
Rates and trends are computed using different standards for malignancy. For more information see malignant.html.
^ All Stages refers to any stage in the Surveillance, Epidemiology, and End Results (SEER) Summary/Historic Combined Summary Stage (2004+).
Φ Rural-Urban Continuum Codes provided by the USDA.
* Data has been suppressed to ensure confidentiality and stability of rate estimates. Counts are suppressed if fewer than 16 records were reported in a specific area-sex-race category. If an average count of 3 is shown, the total number of cases for the time period is 16 or more which exceeds suppression threshold (but is rounded to 3).
Source: SEER and NPCR data. For more specific information please see the table.
Data for the United States does not include data from Indiana.
Data for the United States does not include Puerto Rico.
When displaying county information, the CI*Rank for the state is not shown because it's not comparable. To see the state CI*Rank please view the statistics at the US By State level.
