The Claim
In adult populations from iodine-deficient regions of Russia, thyroid nodules are predominantly benign, with 97% classified as colloid nodules (Bethesda category II) and only 3% classified as Bethesda category IV, indicating low cytologic suspicion for malignancy.
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.
Most thyroid lumps in adults from iodine-poor areas of Russia are harmless, and only a tiny fraction look suspicious for cancer under the microscope.

1 studyStudy: Structural and morphologic characteristics of nodular goiter in chronic iodine deficiency status
The study looked at thyroid nodules in adults from iodine-poor areas of Russia and found that nearly all were harmless, just like the claim says.
