The last week of May in every year is the International Thyroid Knowledge Week, a global thyroid health awareness campaign promoted by the International Thyroid Alliance aims to increase public awareness of thyroid disease, thereby improving the rate of thyroid disease visits and treatment rates. From 21ST May to 27TH May of this year is the 10th International Thyroid Knowledge Week. In recent years, the prevalence of various diseases such as thyroid nodules, thyroid cancer, and Hashimoto's thyroiditis has been increasing year by year, especially among women and the elderly. Most thyroid diseases have no obvious clinical symptoms, which may cause missed diagnosis and misdiagnosis, and thyroid diseases are closely related to many common diseases such as coronary heart disease, cerebral infarction, diabetes, and hypertension. Therefore, it is urgent and worth a long way to improve the awareness of the thyroid gland, the popularization of thyroid science knowledge and the prevention and treatment of cancer.
