In brief: Not likely

The natural exposure one might get just from where you live may exceed 3msv per year. Living in denver, you might be exposed to 6msv per year. Risk of developing cancer from a properly conducted ct scan is low.
I believe the estimated average radiation exposure for a single chest ct is about 5-7msv. A low dose chest ct is about 2msv.
