Counties with the highest melanoma incidence rates in Iowa
Among 87 Iowa counties with published values, the counties with the highest melanoma incidence rates are Mitchell County, IA (54.1, 2.27 times the U.S. rate of 23.8), Sioux County, IA (53.3, 2.24 times the U.S. rate of 23.8) and Montgomery County, IA (53.1, 2.23 times the U.S. rate of 23.8). Values are per 100,000, age-adjusted. 51 of the 87 are significantly above the U.S. rate.
Source: NCI and CDC State Cancer Profiles, both sexes, all ages. These are county-level figures, age-adjusted as published by the source, compared with the U.S. rate. A high rate does not prove an environmental cause: age, smoking, income, access to care, screening and chance all move county rates, and small counties swing widely. Significant means the lower bound of the county’s 95 percent confidence interval is above the U.S. rate.
