@kerry Thyroid cancers account for only 1.5% of all cancers in adults and 3% of all cancers in children. In females, however, thyroid cancers are the seventh most common cancer, comprising 3% of all cases. Although the rate of new cases had been increasing in recent decades, the incidence rate declined by 2.5% per year from 2014 to 2018, due in part to the adoption of more conservative diagnostic criteria.
The American Cancer Society (ACS) estimates that in 2022, 43,800 new thyroid cancers will occur, 31,940 in women and 11,860 in men; the ACS estimates that 2230 deaths from thyroid cancer will occur, 1160 in women and 1070 in men. The highest incidence of thyroid carcinomas in the world is found among female Chinese residents of Hawaii.
Of all thyroid cancers, 74-80% of cases are papillary cancer. Follicular carcinoma incidences are higher in regions where goiter is common.
