Counties with the highest thyroid cancer incidence rates in Maryland

Among 23 Maryland counties with published values, the counties with the highest thyroid cancer incidence rates are Dorchester County, MD (19.5, 1.5 times the U.S. rate of 13), Frederick County, MD (17.4, 1.34 times the U.S. rate of 13) and Kent County, MD (17.2, 1.32 times the U.S. rate of 13). Values are per 100,000, age-adjusted. 4 of the 23 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.
