When i was you younger (22-25 am 32 now) i had a large number of ct scans, vq scans, etc. , probably 20 or 30 ... how high is my cancer risk now? :(

Little higher: Slightly higher than the normal population. Follow up with your doctor routinely to prevent things before they happen.

Hard to say.: Evidence on this topic is largely based on survivor data of the wwii atomic bombs in japan. The problem is that a medical scan is not the same thing as being near an atomic blast; this would seem like common sense to me.
