How long does it take for thyroid cancer to spread?

The 5-year survival was 77.6% in patients with single-organ metastasis and 15.3 % in patients with multi-organ metastases. The average interval between the first and second metastases was 14.7 months. Progression from single- to multi-organ metastases occurred in 76% of patients at 5 years.
