Using CT scan for different parts of the body multiple times can affect the lifetime risk for cancer, notes Radiology Info. For example, multiple CT scans of the abdomen and pelvis region with or without contrast can have a moderate lifetime risk for fatal cancer. The risk is higher in children with this imaging procedure, relates ABC News.
