We consider the effects of full body CT scans on healthy people. New research says that elective full-body computed tomography (CT) scans can increase a person's risk of cancer. "The radiation dose from a full-body CT scan is comparable to the doses received by some of the atomic-bomb survivors from Hiroshima and Nagasaki," wrote the authors of the study in the journal Radiology.
