There exist both type I and type II errors, yes. But it's not absurdity, the South Korean Thyroid Cancer "epidemic" is one of the classic examples of the dangers of using traditional treatments on the lower-severity cases more advanced scanning uncovers. It was a public health disaster with lifelong consequences for those impacted, and was, legitimately, people getting cancer treatment for small cancers so harmless that they would have died of something else before becoming symptomatic.
