In the United States, the incidence of thyroid cancers has risen steadily from the 1970s to the present, with the increasing incidence in part due to the incidental detection of small tumors. There are also data indicating that the incidence of larger tumors is on the rise, suggesting that additional factors, such as environmental exposures, are leading to a true rise in incidence. Thyroid cancer is three times more prevalent in women than men, whereas higher mortality is seen in men.
