Figure 2. Merkel cell carcinoma disproportionately impacts individuals >=65 years of age.

Figure 2

A) Incidence rate by age. Incidence rate by age is shown for Merkel cell carcinoma (green circles, per 100,000 persons) and melanoma (purple triangles, per 6,667 persons). Unlike for melanoma, the incidence rate of MCC increases in individuals >= 85 years of age. N=6,600 cases of Merkel cell carcinoma and 251,437 cases of melanoma (all cases reported to SEER between 2000–2013 with associated age and sex information). 95% confidence intervals are shown. B) Relative incidence in men and women by age. Both MCC and melanoma have a strong male predominance in the oldest individuals. There are insufficient cases of MCC below age 50 to determine whether women in the ‘Gen-X’ and ‘Millenial’ generations will be at higher MCC risk relative to men, as they are for melanoma. Year 2013 only is shown due to rapid changes in melanoma risk for young women. Note that Y axis is on logarithmic scale.
