In : In a word, no. A single ct scan is exceedingly unlikely to cause you any problem of any kind at any point in your life. It is not possible to say that there is no risk at all, because any exposure to radiation (including cosmic radiation from the sun or from naturally occurring radiation that's all around us) can potentially cause a cancer.

You : You are among an increasingly large number of patients who have very appropriate questions regarding the safety of medical imaging and in particular cat scans (ct scans). The issue is fairly complicated. I often refer my patients to a website that helps to explain the risk of radiation from medical imaging and will also log your exposure. It is a very helpful tool to increase your understanding of the small risks associated with imaging. http://www.xrayrisk.com/ in general, exposure to radiation from medical imaging minimally increases your lifetime risk of developing cancer. However, this additional risk is extremely small and increases your risk of developing cancer by an almost negligible amount. To answer your question more pointedly, the risk from a single exposure of a small dose of radiation is so small you should not be concerned.
