Are cancer rates increasing in US?

[Bernard L Cohen <blc+@pitt.edu>]

The position of ACSH on incidence rates vs mortality rates is as follows:

Reported increases in incidence rates are difficult to interpret because
they can reflect any combination of the following:

1. changes in diagnostic criteria
2. more disease surveillance
3. better reporting of cases
4. increases in screening for disease
5. increased utilization of medical services
6. true increases in disease incidence

There are problems in interpreting mortality data as well, but I don't
think they are as big as the problems in interpreting incidence data.
