Notes:

• Created by statecancerprofiles.cancer.gov on 07/18/2025 7:30 pm.
• Regression lines calculated using the Joinpoint Regression Program (Version 5.3.0).
• ¹ The APC is the Annual Percent Change over the time interval. Rates used in the calculation of the APC are age-adjusted to the 2000 US standard population (19 age groups: <1, 1-4, 5-9, ... , 80-84, 85+).


• Explanation of the Calculation of the Trend:
  If the APC is less than -1.5, the trend is falling.
  If the APC is between -1.5 and -0.5, the trend is slightly falling.
  If the APC is between -0.5 and 0.5, the trend is statistically stable.
  If the APC is between 0.5 and 1.5, the trend is slightly rising.
  If the APC is greater than 1.5, the trend is rising.

Rates calculated by the National Cancer Institute using SEER*Stat. Rates 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. Population counts for denominators are based on Census populations as modified by NCI. The US populations included with the data release have been adjusted for the population shifts due to hurricanes Katrina and Rita for 62 counties and parishes in Alabama, Mississippi, Louisiana, and Texas.
