B-ultrasound of thyroid cyst can detect whether there are cancer cells in the cyst, while hyperthyroidism can be judged by checking the level of thyroid hormone, and the two diseases can affect each other.

Thyroiditis is a common thyroiditis, characterized by lymphocyte infiltration and eosinophilia in the cytoplasm of follicular epithelial cells, which usually causes swelling and pain in the pharynx, and may lead to thyroid cancer if not treated in time.

Hyperthyroidism is a disease caused by the thyroid gland secreting too much thyroid hormone. Excessive thyroid hormone can cause a series of clinical manifestations, such as fear of heat, hyperhidrosis, hyperhidrosis, emaciation, palpitation, emotional tension and impatience.
