In this episode from the Endocrine Surgery team at BTK we discuss the clinical applications of genetic testing for thyroid cancer. We walk through three cases of thyroid nodules and discuss why and how genetic testing can guide surgical and medical management. As usual we review key points such as imaging criteria for thyroid nodules, the Bethesda system for thyroid cytopathology, and MEN syndromes. We also go into a more nuanced discussion of how progress in genetic testing has led to more variability in management options.
