CT Scans: Weighing the Tiny Cancer Risk Against Significant Diagnostic Benefits

A new study suggests that while CT scans slightly increase cancer risk (approximately 0.1%), the benefits in disease diagnosis and treatment far outweigh this risk. Experts advise that when a doctor recommends a CT scan, patients should proceed, as the potential benefits in diagnosing illness far outweigh the small added cancer risk. However, the study also notes the increase in CT scan use in recent years and suggests doctors should more carefully weigh risks and benefits, considering diagnostic algorithms and alternative imaging technologies like ultrasound and MRI, and involving patients in the decision-making process.
