Thyroid cancer is not that the younger the patient is, the better the treatment effect is. The therapeutic effect of thyroid cancer is related to many factors such as pathological type, individual physique, timing of treatment, treatment method, etc. It is not that the younger the patient is, the better the therapeutic effect will be. Generally speaking, if papillary thyroid cancer and follicular thyroid cancer patients can be actively treated by surgery at the early stage of the disease, most of them have better prognosis. If the patient has medullary thyroid carcinoma, the prognosis is not as good as that of papillary thyroid carcinoma due to the possibility of invasion of lymph nodes in the neck and metastasis in the bloodstream, but the prognosis of young or middle-aged people with strong physical condition is usually better than that of young people with poor physical condition. In case of undifferentiated carcinoma, the prognosis of both young and middle-aged people is worse, and the median survival period is only 7-10 months. In order to improve the therapeutic effect and prolong the survival time, patients should actively cooperate with professional doctors for treatment.
