Figure 2

Comparison of normalized incidence and mortality rates between age 20–49 and 50 and older by tumor subsite, 1980–2016.Rates of individuals age 20–49 and 50 and older from 1980–2016 from SEER9 were normalized to the 1980 rate to better visualize the magnitude of differences in incidence and IBM trends by age over time. Normalized rates were divided into 10-year age intervals: 20–29 (a), 30–39 (b), 40–49 (c), 50–59 (d), 60–69 (e), 70–74 (f), and 75+ (g).
