After the diagnosis of thyroid malignant tumor, the specific survival time is related to the type of tumor, malignancy degree, tumor size, patient’s physical condition, etc., which cannot be generalized. If the malignancy of thyroid malignant tumor is low, detected early and the tumor is small, the long-term survival rate of patients is higher after effective treatment. If the thyroid malignant tumor is found late, the tumor is large but the malignancy degree is low, the survival time of patients may also be relatively long if they can undergo reasonable and effective treatment. However, if the tumor is more malignant, the patient’s survival period is usually shorter, maybe only six months to a year. At this time, if the patient is not in good health and the disease develops rapidly, the patient may only have a few months of survival. If thyroid malignant tumor can be detected early, it can be cured or prolong life through effective treatment. When thyroid malignant tumor is found, you should go to oncology department as soon as possible, actively cooperate with the treatment, adjust your mentality, enhance your resistance, improve your quality of life and prolong your survival time.
