Malignant thyroid tumors can usually be cured after surgery, but some tumors with poor pathology may not be cured after surgery. In the clinic, the more common malignant thyroid tumors are papillary thyroid cancer and follicular thyroid cancer, whose differentiation degree is generally better, and the development of the disease is relatively slow, such as in the early stage can be timely surgical resection of foci, and standardized comprehensive treatment during the operation. It is possible for patients with this type of disease to be cured. However, in case of medullary thyroid carcinoma or undifferentiated thyroid carcinoma, because of the higher degree of malignancy, its disease development is relatively rapid, and once it is found, it is often in the advanced stage, and there is no effective treatment, and the overall prognosis is still poor after conventional tumor treatment, and this kind of tumors is unlikely to be cured, and the possibility of curing is relatively small. Whether or not a cure can be achieved after surgery for thyroid malignant tumors is closely related to whether or not regular review is performed, in addition to the typing of the tumor and whether or not regular medication is used by the patient after surgery. Suffering from thyroid tumor, it is recommended to seek medical treatment in time and standardize the treatment under the guidance of professional doctors, so as to avoid delaying the condition.
