Cancer mortality in Carroll County is 144.1 deaths per 100,000 people per year against a U.S. rate of 143.2. The strongest disease signals are Melanoma of the skin deaths at 2.2 times the U.S. rate and Lung & bronchus deaths at 1.2 times the U.S. rate. Federal databases place 295 regulated facilities, sites and hazards inside the county, led by Rail grade crossing (89), NPDES wastewater discharge permit (71), Air permit holder (minor source) (41). EPA AirToxScreen estimates a lifetime cancer risk from outdoor air toxics of 20 in a million, driven mainly by formaldehyde.

Rates are age-adjusted per 100,000 people. A cancer signal is marked significant when the lower bound of its 95 percent confidence interval is above the U.S. rate. Facility counts use active federal records located inside the county boundary. Approximate county center: 43.8818, -71.277.
