CT scans have revolutionized medical diagnostics — but could their increasing use be silently fueling a rise in future cancer cases?
A new study highlighted by Justin Stebbing, Professor at Anglia Ruskin University, and originally published by The Conversation on April 16, 2025, raises concerns about long-term cancer risk from frequent CT scan exposure.
CT scans offer fast, detailed internal imaging to diagnose cancer, strokes, and trauma — but they also emit radiation. The study warns of a possible future cost if overused, particularly among children and those needing repeated scans.
The research urges healthcare providers to balance benefits with risks. Although individual exposure is typically low, cumulative effects may raise cancer odds, prompting the need for awareness and safer scan use protocols.
Experts agree CT scans should remain an essential diagnostic tool — but should only be used when medically necessary. Avoiding excessive scans and advancing safer technologies could reduce long-term harm.
As the healthcare industry continues to evolve, ongoing research and innovation may help reduce risk while maintaining diagnostic accuracy. The key message? Scan smart, not just often.
