From the day thyroid cancer is diagnosed to the day after thyroid surgery, thyroid cancer patients are always obsessed with this problem and carry a heavy psychological burden, which is related to your lack of understanding of this disease. Let’s find out what is thyroid cancer? Thyroid cancer is a relatively common malignant tumor of the thyroid gland, accounting for about 1% of all malignant tumors in the body. There are four common pathological types: 1, papillary carcinoma. It accounts for about 60% to 70% of thyroid cancer in Asian adults and is a low-grade malignant tumor; 2, follicular carcinoma. It is slightly less malignant than papillary carcinoma and is moderately malignant. It has a tendency to grow faster and invade blood vessels, leading to hematogenous metastasis, but in general, it and papillary carcinoma are collectively called differentiated thyroid cancer. It is also moderately malignant and can metastasize via lymphatic and hematologic routes, and its prognosis is not as good as papillary carcinoma, but it is not the most malignant. It is the most malignant type of thyroid cancer, and patients usually do not survive more than one year. Therefore, surgery is not recommended. Except for undifferentiated carcinoma, as long as the detection is not too late, type 1, 2 and 3 can be treated by radical thyroid cancer surgery to achieve complete cure or basic cure. Especially papillary carcinoma, as mentioned above, about 70% of Chinese people have papillary carcinoma. This type of thyroid cancer is well differentiated and less malignant, and if a standardized radical thyroid cancer surgery (total resection of the affected side + isthmus + partial resection of the opposite side + lymph node dissection of the sixth region) is done, the prognosis of thyroid cancer is much better than that of other malignant tumors (such as lung cancer, liver cancer, ovarian cancer, etc.). In other words, the recurrence rate after surgery is low, the quality of life and life expectancy are not affected, and most of them will not recur again for life with strict adjuvant oral euthyroidism, which is the best type of thyroid cancer inside, so you should not be nervous. The above three types of thyroid cancer that we have done rarely recur. Therefore, patients with thyroid cancer should face it with a positive attitude, actively cooperate with doctors for treatment, and according to the indications, adjuvant oral eugenol, radiation therapy and low iodine diet, the prognosis of thyroid cancer is relatively good.
