Thyroid cancer represents the most prevalent malignancy of the endocrine system, with its incidence exhibiting a significant rise in recent years. Diagnostic methods have undergone profound evolution over the past century, progressing from basic clinical examination to a sophisticated and technology-centered approach. Initially, the diagnosis of thyroid neoplasms relied on physical examination and palpation, with definitive diagnoses being stated after postoperative histopathological analysis. The mid-twentieth century brought the emergence of imaging techniques, including radionuclide scanning and, later, high-resolution ultrasound, which revolutionized non-invasive detection, enabling earlier and more precise identification of thyroid lesions. The subsequent introduction of fine-needle aspiration (FNA) cytology fundamentally transformed diagnostic algorithms, optimizing preoperative risk stratification and reducing the number of unnecessary surgical interventions. This review outlines the historical development of thyroid cancer diagnostics and highlights major clinical practice milestones.
