I've known this for years. Your doctor may have ordered too many X-ray's or CT scans on your body, increasing the risk of cancer, particularly leukemia, thyroid, and breast cancers. Children are at significantly higher risk, because (as a medical professional friend told me) their bone marrows are still developing. Next time when you visit your doctor, refuse or question the decision to take X-ray. Read Dr. Weil's latest article at
http://www.drweil.com/drw/u/QAA400702/Too-Many-CT-Scans.html
"doctors order all these scans not for medical reasons but to protect themselves from the ever-present threat of malpractice litigation... the owners of for-profit health care centers must use them [X-ray or CT scanners] a lot to recoup their investment."
Unfortunately, there's nothing you can do once the genes are already damaged by the X-rays.
CT's are much stronger X-rays, in case you don't know. For the dosage and their risk, see "Table: Average Radiation Doses Associated With Common Imaging Studies" at

(It needs an account, which is free.)
For your convenience, this is the interesting part of that article,
