Tumors can grow in the thyroid gland, including benign thyroid adenomas, such as follicular adenoma and papillary cystadenoma, and malignant thyroid cancers, such as papillary carcinoma, follicular carcinoma, medullary carcinoma, undifferentiated carcinoma, etc. Thyroid adenomas develop slowly, are smooth and painless, and do not invade surrounding tissues. Thyroid adenoma, with slow development of disease, smooth texture, no pressure and pain, will not invade the surrounding tissues. When thyroid adenoma increases to a certain extent, it can compress the esophagus and trachea, and cause respiratory difficulties and swallowing difficulties. Thyroid cancer, with rapid development of the disease, hard texture, not smooth, can be accompanied by lymph node metastasis in the neck, can invade the surrounding tissues, causing respiratory difficulties, hoarseness, and bone metastasis at the later stage, which can easily lead to bone fracture. Thyroid tumor treatment, it is recommended to carry out surgical resection as early as possible to avoid malignant proliferation, advanced patients, radiotherapy, targeted drug therapy.
