tracey, I wonder why you have so many x-rays within such a short time. I don't know what the definition of x-ray is. In my experience, I had x-ray to my teeth and x-ray to my lungs before treatment. As for the head and neck area, I had ultrasound scan, MRI and CT scan. Your doctors should have a detailed record of what tests you have and they are the best people to answer your question.
