X-rays are a proven cause of human cancer. It is doubtful that you can find any cancer biologists who would deny that statement. Much of the proof comes from the study of people who accumulated their x-ray exposure from multiple exposures, with each exposure received at extremely low doses. Since the study's publication in November 1999, no one has shown that it overestimates the impact of x-rays in causing cancer and coronary heart disease. Some of the critics have never even looked at the study.
