Do TSH levels change with thyroid cancer?

Frequency of thyroid malignancy increases with serum TSH (2.5% when TSH <0.4 mIU/liter vs. 9.1% when TSH 1.6–3.45 mIU/liter). TSH levels decrease with age as a consequence of development of thyroid autonomy in patients with benign nodular thyroid disease but not in those with PTC. TSH higher in advanced cancer stage.
