Yes, it's negligible either way But doctors have that pesky "do no harm" credo that makes them consider whether the benefit of CT scans is worth the harm of 100 people getting cancer that wouldn't have otherwise gotten it. It is proper for society to examine this without dismissing 100 people getting cancer as "negligible".
