Interpretation of Incidence Rates Data

Incidence Rate Report by State

Breast (in situ) (All Stages^), 2018-2022

All Races (includes Hispanic), Female, All Ages

Sorted by Recentaapc

Explanation of Column Headers
Incidence Rate (95% Confidence Interval) - The incidence rate is based upon 100,000 people and is an annual rate (or average annual rate) based on the time period indicated. Rates are age-adjusted by 5-year age groups to the 2000 U.S. standard million population.

Recent Trends - This is an interpretation of the AAPC/APC:

• Rising when 95% confidence interval of AAPC/APC is above 0.
• Stable when 95% confidence interval of AAPC/APC includes 0.
• Falling when 95% confidence interval of AAPC/APC is below 0.

AAPC/APC (95% Confidence Interval) - the change in rate over time

• Average Annual Percent Change - AAPCs are based upon APCs that were calculated by Joinpoint Regression Program
• Annual Percent Change - APCs calculated in SEER*Stat.

Other Notes

• Larger confidence intervals indicate less stability of the data. This is often due to low counts that are not quite low enough to be suppressed.
• Data is currently being suppressed if there are fewer than 16 counts for the time period.

State Cancer Registries may provide more current or more local data.



† Incidence rates (cases per 100,000 population per year) are age-adjusted to the 2000 US standard population (SEER areas use 20 age groups and NPCR areas use 19 age groups). 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.

‡ Incidence data come from different sources. The Average Annual Percent Change (AAPC) is based on the APCs calculated by Joinpoint. Due to data availability issues, the time period used in the calculation of the joinpoint regression model may differ for selected counties.

Rates and trends are computed using different standards for malignancy. For more information see malignant.html.

^ All Stages refers to any stage. Due to changes in stage coding, Combined Summary Stage with Expanded Regional Codes (2004+) is used for data from Surveillance, Epidemiology, and End Results (SEER) databases and Merged Summary Stage is used for data from National Program of Cancer Registries databases. Due to the increased complexity with staging, other staging variables maybe used if necessary.

⋔ Results presented with the CI*Rank statistics help show the usefulness of ranks. For example, ranks for relatively rare diseases or less populated areas may be essentially meaningless because of their large variability, but ranks for more common diseases in densely populated regions can be very useful. The rates used in CI*Rank are all age-adjusted to the 2000 US standard population using 19 age groups for SEER and NPCR areas. More information about methodology can be found on the CI*Rank website.
