Removing the thyroid tumor through surgery alone reduces signs of DNA damage in the blood, even before any radioactive treatment, indicating that the tumor itself contributes to cellular stress.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether total thyroidectomy causes a reduction in DNA damage markers compared to no surgery in PTC patients, independent of tumor removal or other interventions.
A double-blind RCT of 150 PTC patients with confirmed malignancy, randomized to either total thyroidectomy or active surveillance (no surgery) for 6 months, with serial measurement of MN, NPB, and 8-OHdG at baseline, 1 month, and 6 months, controlling for tumor size and molecular subtype.
Whether patients undergoing total thyroidectomy for PTC show sustained reduction in DNA damage markers over 5 years compared to those managed with lobectomy or non-surgical approaches.
A prospective cohort study of 400 PTC patients stratified by surgical approach (total thyroidectomy, lobectomy, or non-surgical), with DNA damage biomarkers measured at diagnosis, 3 months, 1 year, and 5 years, adjusting for tumor stage, age, and radiation exposure history.
Whether patients who have undergone total thyroidectomy for PTC have lower DNA damage markers than those with untreated tumors.
A cross-sectional comparison of 200 PTC patients who had undergone total thyroidectomy at least 6 months prior and 200 with untreated tumors, measuring MN, NPB, and 8-OHdG levels while controlling for age, tumor size, and comorbidities.
Whether patients with persistent DNA damage after surgery are more likely to have residual disease or recurrence.
A case-control study comparing 100 PTC patients with persistent high DNA damage markers 6 months after thyroidectomy (cases) to 200 with normalized levels (controls), assessing for residual thyroid tissue, recurrence, and molecular markers.
Whether individual cases of PTC show dramatic reduction in DNA damage markers immediately after thyroidectomy.
A case series of 10 patients with PTC undergoing total thyroidectomy, with serial blood sampling for MN, NPB, and 8-OHdG at 24 hours, 7 days, and 30 days post-surgery, with detailed pathological confirmation.
