title: [Epidemiology of thyroid carcinoma over the world].
abstract: Thyroid cancer (TC) incidence, in France and over the world, has dramatically increased over the last two decades. The temporal and geographical incidence trends in France and in the world are analysed. The increased incidence of TC is actual, mainly due to an increase of papillary microcarcinomas. The spread of ultrasonographic and cytological procedures, the extensiveness of thyroidectomies lead to diagnostic advance, to a better preoperative selection of patients and to the discovery of occult microcarcinomas. Nevertheless, the impact of the risk factors of thyroid cancer on the increase of incidence is not excluded. These risk factors are analysed, especially environmental chemicals agents that disrupt thyroid function.
