Increasing Incidence of Colorectal Cancer in Young Adults

Figure 4

Trends in colon tumor subsite-specific incidence rates stratified by age, 2000–2016.Age-adjusted incidence rates per 100,000 persons from 2000–2016 were derived from SEER18 program data. Colon cancer incidence trends were calculated for individuals age 20–29 (a), 30–39 (b), and 40–49 (c). Annual percentage change (APC) are quantifications of the changes in trends. Asterisks () designate statistical significance calculated in the permutation model.
