Hi Lisa- I'm a 25 lung cancer survivor. I have multi-focal adenocarcinoma lung cancer. There is limited data showing the dangers of mortality from radiation exposure. There is also a difference between the sexes. Not one doctor in my many years of lung cancer has ever mentioned any danger from CT scans. There are, however, side effects from the contrast and if you or anyone here have them there are medications to help. I have to take Zofran because I have a tendency to feel very nauseous. And I'd rather not feel that way, especially if I might hear bad news after the scan is finished.

The longer that I am a patient the more screwy I find the time in between scans. Yes, insurance companies are one reason for possible delays but also the type of cancer and the hospital's recommendations, and the doctor's experience. But there is one other source for that decision and that is the radiologist who reads the scan and who writes up a report.
