Oral contrast or IV contrast for CT scans abdomen, pelvis, lungs?

I am the same - always IV contrast and no shielding. I can’t count how many scans I’ve had over the last 3 years. I’ve been on quarterly PET-CT surveillance scanning over the last 12 months.

I read that these scans may possibly cause cancer themselves, but that their use outweighs the risks. I wonder if anyone else has heard that?

Yes - I've been told the same.

I'm thinking that over the decades that x-rays/CT scans have been used, the amount of radiation exposure has greatly been reduced.

Example: my dentist still uses shielding when using his x-ray over the chair, but he also has a newer x-ray device that you step up to and it rotates around your mouth - that doesn't require any shielding.
