A new study found that CT scans may be linked to a much larger number of future cancer cases than many people expected. The study estimated that about 93 million CT scans were performed in the United States in 2023. Based on radiation exposure from those scans, researchers projected that they could contribute to about 103,000 future cancer cases. That number would equal roughly 5% of all new cancer diagnoses from that year, making the issue important at a public health level. The risk from a single CT scan is still considered low for most people. However, when millions of scans are done each year, the combined impact can become significant. Infants and children face a higher risk per scan because their bodies are still developing and they have more years ahead for radiation-related cancers to appear. Even so, most of the projected cancer cases are expected to occur in adults. This is mainly because adults receive far more CT scans overall. The cancers most often predicted from CT-related radiation include lung cancer, colon cancer, leukemia, and bladder cancer in adults. In children, the study pointed to thyroid, lung, and breast cancers as important concerns. Experts say CT scans can be lifesaving and should not be avoided when they are truly needed. The concern is unnecessary scanning or using more radiation than needed for a clear result. The main message is that doctors should order CT scans carefully, avoid scans that are not medically necessary, and use the lowest radiation dose that still gives useful images.
