It is not common to get brain tumors. It is even less common to get anything as a result of radiation given from scans of any type.
I suggest that you speak to your doctor about the risks that may be individual to you but in general, they are very very very low. Not everything that you read (despite the commercial) is true. After all, radiation is everywhere - sunshine is radiation! An airplane ride typically gives you more radiation than a CT scan.
If it was high, I would surely have a brain tumor. I can't even count how many CTs and MRIs that I have had - even a PET scan which is even more radiation. Plus I have flown a lot. Not something I am worried about.
