Single CT Scan Prolongs Survival by Extending Cancer Latency in Trp53 Heterozygous Mice

There is growing concern over the effects of medical diagnostic procedures on cancer risk. Although numerous studies have demonstrated that low doses of ionizing radiation can have protective effects including reduced cancer risk and increasing lifespan, the hypothesis that any radiation exposure increases cancer risk still predominates. In this study, we investigated cancer development and longevity of cancer-prone Trp53^+/- mice exposed at 7-8 …
