So there really isn't that much more risk of developing cancer if you've had a barium swallow and get a chest ct scan done?

Well there are othe: There can be other malignancies not picked up by those studies. Have your physician help guide you.

True: The amount of radiation one receives from those two studies is very small altogether. Although certainly any radiation carries some risk, the amount here is minuscule. The chances of getting cancer from this are almost nil. Hope this helps.
