The Claim
Between 1999 and 2008, the incidence of clinically detected thyroid cancers increased dramatically, with 99.9% of this increase consisting of tumors smaller than 20 mm, a size too small to be reliably detected by physical examination, indicating that many of these 'clinically detected' cases were likely identified incidentally during screening.
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.
More thyroid cancers were found between 1999 and 2008, but almost all of them were tiny lumps that doctors couldn’t even feel during a regular checkup — so they probably found them by accident while doing scans or tests for other reasons.
See the scientific wording
The incidence of clinically detected thyroid cancers also increased dramatically between 1999 and 2008, with 99.9% of the increase being tumors less than 20 mm — a size too small to be reliably detected by physical examination, suggesting many 'clinically detected' cases were actually found incidentally during screening.
What the research says
1 studyDoctors found way more tiny thyroid cancers after they started using ultrasounds to scan people who felt fine — but these tiny cancers would never have been found otherwise. The study proves most of the increase wasn’t from real disease growth, but from over-testing.
