CT scan radiation risk comparable to alcohol and obesity: study

Repeated exposure to unnecessary CT (computed tomography) scans may increase cancer risk to a level comparable with alcohol consumption and obesity, a new study has found. The research, conducted by scientists at the University of California-San Francisco (UCSF), estimated that radiation from CT scans contributes to about 5% of all cancer cases annually.
