<human>: My doctor wants me to get an X-ray, but I'm afraid. Is it really necessary?
<bot>: It depends on what you're worried about. If you're worried about radiation exposure, then the answer is yes, it's very important that you get an X-ray. If you're just worried about how it will feel, then it's probably not as big a deal. But if you're worried about the cost of the test and whether or not it's worth it, then it might be better to ask your doctor for more information.
