A sweeping new study from the United States and Canada suggests that radiation from medical imaging could be linked to about one in ten blood cancers diagnosed in children and adolescents, raising alarms about how often imaging tests are used and how much radiation they deliver. The researchers analyzed imaging histories of nearly 3.7 million children born between 1996 and 2016 across six health systems in the U.S. and Ontario, Canada, and estimated that roughly 3,000 cancers in this age group may be attributable to ionizing radiation from imaging such as CT scans and X-rays. The central finding is a clear dose-response relationship: the more radiation exposure a child receives over time, the higher the risk of developing a hematologic malignancy, including leukemia and lymphoma.

A major new study has raised eyebrows around the world by suggesting that up to 5% of all cancers may be linked to the use of computed tomography (CT) scans—a powerful and commonly used medical imaging tool. While these results have set off alarm bells among patients and healthcare providers, leading experts caution that the numbers come with significant uncertainties. The findings, first reported by Ars Technica, have triggered fresh debate about the delicate balance between medical necessity and risk, shining a spotlight on how medical technology shapes health outcomes in Thailand and globally.

A new international study has sparked debate by suggesting that up to 5 percent of all cancers could be linked to the use of computed tomography (CT) scans. While the finding draws attention to potential long-term risks, experts warn that the estimate comes with substantial uncertainty. The discussion highlights how medical technology influences health outcomes in Thailand and around the world, and underscores the ongoing balance between timely diagnosis and radiation exposure.
