I was directly referencing the parent comment: > At the same time, everybody seems to accept that the chance of getting cancer in your lifetime has risen to about one in three for men and one in five for women. Which suggests that there is an apparent increase in cancer rates. So yes, I was referring to an incident rate. Regardless, the semantics here don't change the meaning of my statement. We have solved (for lack of a better word) many of the lower hanging fruits of human disorders. As such, we can't effectively control for incidence rates over time
