RecruitingClinical trialDiagnostic DNA Methylation Signature in Diagnosing Thyroid Cancer After Fine-Needle Aspiration in Patients With Thyroid NodulesThis trial studies how well the diagnostic deoxyribonucleic acid (DNA) methylation signature works in detecting thyroid cancer in patients with thyroid nodules. Using diagnostic testing, such as the diagnostic DNA methylation signature, may be a less invasive way to check for thyroid cancer.
