That’s what I figured as well… Especially since cancer death rates have been slowly, but steadily declining.
Cancer Death Rate Continues Steady Drop
More than 1.7 million cancer deaths averted between 1991 and 2012
Edit:
As a percentage of the population, Cancer deaths went from 0.14% in 1950 to 0.19% in 2011; Heart disease went from 0.35% in 1950 to 0.19% in 2011.
If one normalized for life expectancy, I doubt that there would be much change in the cancer rates.
