When lymph node metastasis occurs in cancer, it may be intermediate or advanced, but it is not certain exactly what stage it is, for example, stage III or IV is more common. There are local lymph node metastasis and distant lymph node metastasis. If there are only local lymph node metastases and the number of metastases is relatively small, it is possible that the metastases are stage II or stage III. If there is distant lymph node metastasis, it usually belongs to stage IV, that is, advanced stage. Once lymph node metastasis appears, it indicates that the disease is progressing, and the disease is not too early, but there is still hope for surgical cure, mainly by enlarged resection of the primary tumor lesion, plus regional lymph node dissection. If there is already distant lymph node metastasis, there is no way to do surgery for radical cure, but only to cooperate with systemic chemotherapy, targeted therapy, local radiotherapy and other treatment methods.
