Counties with the highest thyroid cancer incidence rates in California
Among 48 California counties with published values, the counties with the highest thyroid cancer incidence rates are Plumas County, CA (17.8, 1.37 times the U.S. rate of 13), San Benito County, CA (17.2, 1.32 times the U.S. rate of 13) and Kern County, CA (16.1, 1.24 times the U.S. rate of 13).

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.
