FTC occurs more frequently in whites than in blacks. The incidence is higher in women than men by a factor of 2-3 or more. The ratio varies by patient age:

  • In patients younger than 19 years, the female-to-male ratio is 4:1
  • In patients aged 20-45 years, the female-to-male ratio is 3:1
  • In patients older than 45 years, the female-to-male ratio is 4:1

In postmenopausal women, a weak positive association (relative risk < 1.20) has been found between increased body mass index and thyroid cancer. [11]

Thyroid carcinoma occurs in all age groups, but is most  diagnosed in persons aged 45–54 years. Median age at diagnosis is 51 years. [12] In older adults, FTC tends to occur more often than papillary thyroid carcinoma.
