Hello, I have a general concern about radiation. My 15 year old daughter has had a bad year. She had a sports inury that led to 2 Xrays, one foot, one shin. Recently, she was in the ER due to suspected apendicitis. The doctor ordered an abdominal CT scan. Besides these, she had a couple of dental x rays in the past. Now I feel like I have raised her risk for cancer. I hate to have this worry. But thought I'd look for advice here. Thank you to all who take a moment to respond.
