Journal of Clinical OncologyPre-existing Thyroid Autoimmunity and Risk of Papillary Thyroid Cancer: A Nested Case-Control Study of US Active-Duty Personnel

These authors found a “consistent positive association between pre-existing thyroid autoimmunity and higher thyroid cancer risk.” There also appears to be a correlation between thyroid antibody levels and related risk. The association appeared stronger in women than in men. The authors do not recommend screening for thyroid cancer in those with thyroid autoimmunity because of the risk of overdiagnosis.
