I stand corrected. I think the legend part is that age-adjusted cancer
rates (other than smoking-related) have been increasing. Age adjustment is
important since cancer is, in part, caused by age. As people become
healthier and live longer, cancer rates will go up, all else being equal.
I would encourage people to look at the data.
