A 28y old (me) had a fish bone stuck in throat to remove dr use ct scan and x-ray and perform endoscopy to remove but now i am scared can this lead to cancer whats my chances of developing cancer from ct with out contrast? worried now?

Not measurable: The radiation for a CT scan will not increase your risk of cancer over your baseline risk, by a measurable amount. Each examination has risk and benefits and a balance needs to be struck. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.
