Thyroid cancer is a common malignant tumor in the head and neck area. Early symptoms and signs primarily include a thyroid mass discovered incidentally during a physical examination. This type of mass grows quickly, leading to localized thyroid enlargement, and patients may experience discomfort when swallowing. Additionally, some thyroid cancer patients, due to abnormal hormone secretion, might experience unexplained skin flushing or sweating symptoms. Besides, early symptoms and manifestations of thyroid cancer are not typical, and many patients do not exhibit obvious symptoms. Instead, abnormalities in thyroid function are often incidentally found during physical examinations.
