>"Given that this study focuses on declining naive T cell production and thymic tissue loss, it is interesting to look at another recent study that suggests these losses are the dominant cause of increased cancer rates with age. [...] Our model outperforms the power law model" Interesting, since cancer "rates" (age-specific incidence) for many cancers peak at 60-90 years old. This paper looks like they cut off the data at 85 years, ignore the peaks during youth, and aggregate the data in such a way (eg colon and rectum grouped together) to force a power law fit. EDIT: Also, they just say "data from SEER". What years did they use, inclusion criteria, etc?
