A member asked:

Can chest ct scan puts me at the higher risk of thyroid cancer? chest ct was done with contrast. can contrast used in chest ct damage thyroid?

A doctor has provided 1 answer

Yes, no: There is some evidence that chest ct could put one at higher risk for thyroid cancer - but almost all of these suggest that it is dose dependent and that it would take repeated scans/exposure to elevate the risk. You can request protective covering for thyroid if need additional scans. The contrast used will not cause thyroid damage or disease.
