"† Incidence rates (cases per 100,000 population per year) are age-adjusted to the 2000 US standard population [http://www.seer.cancer.gov/stdpopulations/stdpop.19ages.html] (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 [http://seer.cancer.gov/popdata/] by NCI. The US populations included with the data release have been adjusted for the population shifts due to hurricanes Katrina and Rita [http://seer.cancer.gov/data/hurricane.html] for 62 counties and parishes in Alabama, Mississippi, Louisiana, and Texas. The 1969-2009 US Population Data File is used for SEER and NPCR incidence rates."
"§ Because of the impact on Louisiana's population for the July - December 2005 time period due to Hurricanes Katrina/Rita, SEER excluded Louisiana cases diagnosed for that six month time period. The count has been suppressed due to data consistency issues.  [http://seer.cancer.gov/data/hurricane.html]

"Interpret Rankings provides insight into interpreting cancer incidence statistics.  When the population size for a denominator is small, the rates may be unstable.  A rate is unstable when a small change in the numerator (e.g., only one or two additional cases) has a dramatic effect on the calculated rate."

Suppression [http://statecancerprofiles.cancer.gov/suppressed.html] is used to avoid misinterpretation when rates are unstable.
