Thyroid cancer is cancer of the thyroid gland.[1]

Classification

Differentiated tumors

The differentiated thyroid cancers are:[2]

  • Papillary
  • Follicular

Poorly differentiated tumors

  • Medullary
  • Anaplastic

Epidemiology

A study of autopsies in Finland found that 36% of subjects had papillary thyroid cancer.[3]

Thyroid cancer may be present 5-10% of patients with thyroid nodules including incidentalomas.[4]

Staging information

Thyroid cancer staging information from the National Cancer Institute's Physician Data Query


Prognosis

Thyroid cancer - survival.

Treatment

Chemotherapy

Chemotherapy is usually reserved for poorly differentiated tumors, medullary[5] and anaplastic[6] thyroid cancer.
