<s>[INST] I'm not a very smart person, so this might seem like a dumb question. I've had about ten ct scans over the past seven years, and about just as many X-rays. Have I put myself in any kind of danger? What are my short term and long term risks of getting cancer? [/INST] Hi, dearI have gone through your question. I can understand your concern.  Ct scan and xray both are injurious to health.  It gives you radiation exposure and radiation causes damage to the cells.  It causes mutation and gives chance of cancer.  Short term risk is not increase much but long term risk is definitely increased. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using health care magic. Wish you a very good health. </s>
