Answer

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 fifth most common cancer, comprising 4% of all cases. [26] In addition, the rate of new cases has been increasing in recent decades. [27]

The American Cancer Society (ACS) estimates that 52,890 new thyroid cancers will occur in 2020, 12,720 in men and 40,170 in women; the ACS estimates that 2180 deaths from thyroid cancer will occur in 2020, 1040 in men and 1140 in women. [26] 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.
