The Claim
The proportion of thyroid cancers detected by screening in South Korea increased from 15% in 1999 to 56% in 2008, and this increase coincided with the rapid expansion of thyroid ultrasound services following healthcare system reforms in 2000.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In South Korea, more and more people started finding thyroid cancer through routine scans between 1999 and 2008 — and this happened right after doctors began using ultrasound machines much more often thanks to new health rules.

What the research says
1 studyMore people in South Korea started getting ultrasound scans for their thyroid after 2000, and that’s why doctors found way more tiny thyroid cancers—not because more people were getting sick, but because they were looking harder.
