Cancer metastasis and spread are a very fearful problem. Metastasis is mainly divided into distant metastasis (other organ metastasis) and lymph node metastasis. Many patients with A-Cancer have found lymph node metastasis after receiving pathological reports. They checked online and said it was very serious. They thought it was in the late stage. They were very nervous. The main reason is that there is less professional content on the Internet, and even some doctors who are not professional in thyroid tumors do not understand it. In addition, the patients themselves have only a little understanding of it, and most of them will think about the bad aspects. The weight of the impact of lymph node metastasis on tumor stage and survival of various tumors is different. So in papillary thyroid carcinoma, is lymph node metastasis serious? What is its status in tumor staging? Does it have a great impact on survival?
1. First, let’s take a look at AJCC Thyroid cancer TNM stage eighth edition:
See if the tumor is serious or not, first understand the tumor stage
Detailed interpretation of tumor stage
See: 
This scoring system does not include the factor in whether lymph node metastasis is considered. It can be seen that lymph node metastasis has almost no effect on the 20-year survival rate.
3. In addition,
thyroid cancer, especially papillary cancer, lymph node metastasis is very common, accounting for 40% to 70%. Moreover, many lymph node metastasis cannot be discovered by ultrasound before surgery, and most of them are found under a microscope after resection. Even if lymph node metastasis in thyroid cancer is common, the ATA guideline of the American Thyroid Association and the NCCN guideline of . do not recommend preventive dissection of central lymph nodes, which is enough to show that lymph node metastasis, especially minor metastasis, does not affect the prognosis of patients with thyroid cancer.
In summary, lymph node metastasis in thyroid cancer is very common, and it has very little impact on tumor stage and survival. Therefore, patients with A-Cancer should not be afraid of their lymph node metastasis, maintain a good attitude, and live a positive life.
