Here’s a concise summary of the news article:

A new study estimates that the rising number of CT scans in the United States – reaching 93 million in 2023 – could cause over 100,000 cancer cases, approximately 5 percent of all cancers. The research, led by The Institute of Cancer Research, London, highlights a significant concern, particularly regarding the 9,700 potential cancers in children linked to CT scans. While individual risks are small and benefits often outweigh the risks when scans are clinically justified, the sheer volume of scans raises worries about increased radiation exposure and potential long-term cancer rates. The study emphasizes the need for careful clinical decision-making, optimized doses, and a reduction in unnecessary scans, particularly those offered by private clinics. The UK’s stricter regulations regarding CT scans – with significantly fewer scans per population – are presented as a model for reducing potential harm.
