Table 1 summarizes number of new cases per 100,000 persons by race/ethnicity and sex.

Annual percent change (APC) is a commonly used indicator for the assessment of changes in incidence. Some prior studies have reported a worldwide increasing trend for thyroid cancer incidence in recent decades. Thyroid cancer is more prevalent among women and those with positive family history of thyroid disease. Detailed epidemiology of thyroid cancerĪs the most common endocrine cancer and fifth most common cancer in women, thyroid cancer includes approximately 1–1.5% of all new cases of cancer diagnosed annually in the USA based on previous data. *Address all correspondence to: 10.5772/intechopen.70128 From the Edited Volumeġ.
