A new study published in JAMA Internal Medicine has raised concerns about the cancer risks linked to CT scans, estimating over 100,000 related cases annually in the United States. The scans expose patients to ionizing radiation, which can damage DNA and increase cancer risk, especially in children and people with genetic conditions such as Lynch syndrome. With 93 million scans performed in 2023, experts emphasize using CT imaging only when truly necessary and recommend considering safer options like MRI or ultrasound.
