Figure 3. Observed and projected MCC incidence.
A) Explanation for ongoing brisk rise in MCC incidence. Projected change in US population based on US census projections (bars) with MCC incidence rate per 100,000 from 2011–2013 (red line) (most recent years of available data) overlaid. The baby boom generation in 2025 is indicated by the bracket (ages 61–79 in 2025) and account for much of the anticipated rise in MCC incidence. B) Observed incidence and projected annual incidence for MCC from 2000–2025, based on SEER-18 data and US census projections. Estimated number of cases in 2015 in the US is 2,472 cases and in 2025 3,284 new cases per year.
