Answer

Thyroid cancers account for 1.5% of all cancers in adults and 3% in children. The European Network of Cancer Registries reports that the incidence varies from country to country: Lithuania reported the highest age-standardized rate per 100,000 population (15.5), followed by Italy (13.5), Austria (12.4), Croatia (11.4), and Luxembourg (11.1). [10] ​ The highest incidence of thyroid carcinomas in the world is among female Chinese residents of Hawaii. In Hawaii, the incidence of FTC ranges from 10-3 new cases a year per million inhabitants.

In recent years, the frequency of FTC has appeared to increase; however, this increase is related to improvement in diagnostic techniques and a successful campaign of information about this carcinoma. [10]

Of all thyroid cancers, 17-20% are follicular. According to world epidemiologic data, follicular carcinoma is the second most common thyroid neoplasm; in some geographic areas, however, FTC is the most common thyroid tumor. The relative incidence of follicular carcinoma is higher in areas of endemic goiter.
