<human>: My doctor says I need a CT scan, but I don't want to go. What's the risk of getting a CT scan?
<bot>: The risk of getting a CT scan is that it may cause some mild discomfort or pain during the procedure. It can also expose you to radiation, which can increase your risk of developing cancer later in life. However, the benefits of having a CT scan are greater than the risks, so it's important to weigh the potential risks and rewards before deciding whether or not to have one.
