Study population: The Thyroid Tumor and Cancer Collaborative Registry (TCCR) is a thyroid cancer and thyroid nodule database at the University of Nebraska Medical Center. The database serves as a registry and biospecimen bank for those who wish to participate in multidisciplinary research. The database will be accessed to query for individuals with a diagnosis of thyroid cancer, both active disease and in remission, as well as a diagnosis of thyroid nodules. Those meeting eligibility requirements will then have their registry information and stored biospecimens accessed for testing and review.

Brief summary: The purpose of this study is to evaluate Vitamin D levels in thyroid cancer patients with active disease compared with thyroid cancer patients in remission and patients with thyroid nodules.

Detailed description: Thyroid cancer is the most common endocrine related malignancy, increasing in incidence in recent years. There are relatively few, well known factors, both genetic and environmental, which predispose to the development of thyroid cancer. Vitamin D deficiency has been associated with other cancers, but the association between vitamin D and thyroid cancer is unknown. We plan to do a case control, pilot study to evaluate the relationship between vitamin D levels and thyroid nodules, thyroid cancer in remission, and active thyroid cancer.

Eligibility criteria: Inclusion Criteria:

* Cases: History of Papillary, Follicular, Follicular Variant of Papillary, or Hurthle cell thyroid cancer (both active disease and in remission).
* Controls: Individuals with a thyroid nodule, matched to cases for age, BMI, season of vitamin D measurement.
* Participating in University of Nebraska Medical Center Thyroid Tumor and Cancer Collaborative Registry database.

Exclusion Criteria:

* Pregnant or breast feeding women
* Medullary thyroid cancer
* Anaplastic thyroid cancer

Primary outcomes:
measure: Number of Persons That Are Vitamin D Deficient in the Thyroid Nodule, Thyroid Cancer in Remission, and the Active Thyroid Cancer Groups.
timeFrame: Within 12 months of enrollment in thyroid cancer collaborative registry (TCCR) database
