It is common knowledge that x-ray studies such as regular x-ray films or CT scans do put out a bit of radiation, and that radiation does not noticeably increase "one particular person's risk of cancer", when added to the radiation risks for cancer she already experiences just by living on Earth. The chance of cancer before and after 2 CT's are the same. We can't tell a difference, so no worries.

Modern CAT scans provide very brief exposure to minimal amounts of radiation, and there is no serious expectation of any development of cancer secondarily.

All the new x-ray units are calibrated for the proper amount of exposure to the area that needs to be examined. No need for lead aprons in most cases.
