More Americans are receiving computed tomography (CT) scans than ever before, with over 30% more exams performed annually since 2007. Researchers warn that unwarranted tests may be exposing the population to unnecessary radiation, potentially leading to cancer risks. A new study predicts that low doses of ionizing radiation from CT scans could account for 5% of all new cancer diagnoses in the US.
According to the study, 103,000 future cases of cancer could be attributed to CT scans conducted in 2023. However, it’s essential to note that these risks are theoretical and based on historical data from high-radiation events. The association between low-level radiation and cancer is still unclear.
While CT scans can save lives, scientists emphasize the need for vigilance around long-term radiation exposure. Experts argue that unnecessary CT scans should be avoided if radiation-free procedures can do the same job. The study highlights the importance of weighing the benefits of CT imaging against potential risks.
