Cancer rates

As people live longer, the chances of them getting cancer increase - so it is hard to know whether there is a signal of environmental degradation in an increased incidence of cancer.

So, look at the incidence of childhood cancer:  Childhood Cancer Epidemiology in North America. (PDF)

It tells us (slide 3) that the overall rate is 165 cases per 1,000,000 children per year; (slide 12) "Overall non-significant 0.4% increase per year 1992-2004".

One can go to the National Cancer Institute's SEER database, and extract information, like this below.  I guess whatever we are doing to our environment, it is not reflected in the childhood cancer incidence rates.
