This problem, however, still lacks adequate attention.</p><p><strong>Methods: </strong>We retrieved the original data of current, past and future burden of thyroid cancer from the Global Cancer Observatory (GLOBOCAN) 2022. We calculated the age-specific mortality-to-incidence ratio (MIR) by dividing age-specific mortality rates by incidence rates to quantify potential overdiagnosis, and used Segi's world standard population to calculate the age-standardised incidence rate (ASIR) and age-standardised mortality rate (ASMR). We then assessed the correlation between the human development index (HDI) and ASIR/ASMR using the linear correlation coefficient (r). Lastly, we characterised the temporal trend with the estimated annual percentage change (EAPC) and project the early-onset thyroid cancer burdens to 2050.</p><p><strong>Results: </strong>Globally, there were an estimated 239 362 (ASIR = 4.00 per 100 000 population) cases and 2409 (ASMR = 0.04 per 100 000 population) deaths from thyroid cancer among individuals aged <40 years in 2022. Compared to its ranking as the 7th most common cancer in the overall population, thyroid cancer rose to become the 2nd most common cancer among individuals <40 years. Nearly 99% of thyroid cancer cases in individuals <40 years of age (MIR = 0.01) may be potentially overdiagnosed, whereas 34% of cases in those >80 years (MIR = 0.66) were overdiagnosed. The ASIR of early-onset thyroid cancer varied widely (from 0.13 to 13.17 per 100 000 population), while the ASMR remains relatively similar and low across different regions. The ASIR of early-onset thyroid cancer increased with HDI (r = 0.69), while the ASMR decreased (r = -0.22). The ASIR of early-onset thyroid cancer had the fastest upward trend (EAPC in males vs. females: 9.88 vs. 9.28%) compared to early-onset cancers at other sites, while ASMR showed a downward trend (EAPC in males vs. females: -0.38% vs. -1.33%). The Republic of Korea experienced the highest EAPC for early-onset thyroid cancer ASIR (males vs. females: 29.95% vs. 23.04%). If national rates from 2022 remain stable, projected cases of early-onset thyroid cancer would decrease in high (-13.3%) and very high (-10.9%) HDI countries, but increase in low (96.5%) and medium HDI countries (11.7%).</p><p><strong>Conclusions: </strong>The trend of early-onset thyroid cancer at the global level is more alarming than that of thyroid cancer overall.
