Evaluation of DNA Methylation Signatures for the Diagnosis and Management of Thyroid Nodules

This clinical trial evaluates deoxyribonucleic acid (DNA) methylation signatures in diagnosing and managing thyroid nodules. The purpose of this research is to develop a new test for thyroid cancer. This test will use needle biopsies (small collections of tissue with a needle) from the thyroid to determine whether the participant has a malignant (cancer) or benign (not showing cancer) thyroid tumor. The information learned from this trial may help develop a more accurate test so that patients do not have unnecessary surgeries for nodules that are thought to be suspicious but are actually benign.
