Thyroid cancer is one of the fastest growing cancers in the United States, with a 240% increased incidence over the past three decades.7 Although the majority of newly diagnosed thyroid cancers are small papillary thyroid carcinomas, all sizes and stages of papillary thyroid carcinomas in both genders and in all ethnic groups exhibit an increased incidence.8 It is the most common endocrine malignancy, accounting for 94.6% of the total new endocrine cancers, and 66.0% of the deaths due to endocrine cancers. Based on cancer statistics, 37,200 new cases of thyroid cancer will be diagnosed in 2010 with a total of 1,630 deaths due to the disease.3      Updated by Tobias Carling (3/26/2012) The latest epidemiological analysis shows a continued increased incidence of thyroid carcinoma with an estimated 48,020 new cancer cases in 2011.
