Well, I read in an article before that you increase your chances of cancer if you are exposed to too much radiation. The amount of radiation that you receive during x-rays can vary depending on the area of the body and intensity that they set the machine to. Supposedly, your doctors should be looking at your medical history to see how much exposure you've had within a certain period of time as there is a safe zone you should stay within over the period of your lifetime. Unfortunately, we have to be our own advocates and the responsibility of this task has fallen on us. There are other machines that use sounds waves and can provide the same information as an x-ray machine but it is costlier for insurance and so therefore not the preferred method. How sad.
