Similarities in the Age-Specific Incidence of Colon and Testicular Cancers

Figure 4

This graph presents the data for colon carcinoma among women in 2000 as collected by the SEER-17 cancer registries for the ages 85–99.

Two lines are shown, one represents the assumption of 100% of the population, the second represents the best fit data from the 0 to 84 years old data, with 12% susceptible. The data points indicate the measured specific incidence for women 85–99 years old. The data points clearly fall upon the 12% line, ruling out the 100% hypothesis.
