'No evidence that CT scans, X-rays cause cancer'
Feb-12-2016

Writing in the American Journal of Clinical Oncology, the researchers describe how the linear no-threshold model (LNT) - first proposed over 70 years ago - is used to estimate cancer risks from low-dose radiation, such as medical imaging.

But - say James Welsh, a radiation oncology professor in the Stritch School of Medicine at Loyola University, Chicago, IL, and colleagues - risk estimates based on the LNT model are only theoretical, and, as yet, "have never been conclusively demonstrated by empirical evidence."

They say persistent use of the LNT model by regulators and advisory bodies leads to unfounded fears and money being wasted on unnecessary safety measures.

As a result, many doctors are averse to recommending and using the most appropriate imaging procedures for their patients, and many patients are unnecessarily scared to undergo them.
