This is evidence for a correlation between the number of CT scans and cancer incidence. To jump to the conclusion that the cancer is caused by the radiation from the CT requires a leap of faith.

The funny thing is, if an epidemiological study shows that low dose ionizing radiation is beneficial (radioactive apartment buildings, nuclear navy workers), it's dismissed by a completely ad-hoc "healthy worker effect" or "healthy student effect". But in a study of people who received a CT scan, where you should expect a "sick people effect" (healthy people don't get CT scans), you "don't see a problem".
