Multiple CT Scans Extend Lifespan by Delaying Cancer Progression in Cancer-Prone Mice

Computed tomography (CT) scans are a routine diagnostic imaging technique that utilize low-energy X rays with an average absorbed dose of approximately 10 mGy per clinical whole-body CT scan. The growing use of CT scans in the clinic has raised concern of increased carcinogenic risk in patients exposed to ionizing radiation from diagnostic procedures. The goal of this study was to better understand cancer risk associated with low-dose exposures …
