Colon and rectal cancer incidence and mortality rates stratified by age, 1980–2016. Age-adjusted incidence and incidence-based mortality (IBM) rates per 100,000 persons from 1980–2016 were derived from SEER9 program data. Colon and rectal cancer incidence and IBM trends of individuals under the age of 50 (a, c) and age 50 and older (b, d). Annual percentage change (APC) are quantifications of the changes in trends. Asterisks () designate statistical significance calculated in the permutation model.
