Scared about having too many ct scans. any data?

Caution: A ct abdomen equals about 500 chest xrays, add a pelvis, another 500. This is 5 years background radiation and exposure is cumulative. Worse when young! think twice about the real need before doing xrays. For more about risks and benefits of ct scans see fda webs: http://www.Fda.Gov/radiation-emittingproducts/radiationemittingproductsandprocedures/medicalimaging/medicalx-rays/ucm115317.Htm.
