Cervical lymphatic metastasis refers to the metastasis of cancer disease through the lymphatic tract metastatic pathway and the formation of secondary cancer foci in the lymph nodes of the neck. Cancer diseases are clinically characterized by metastasis, and common metastatic pathways include local spread, lymphatic pathway, and hematogenous pathway. Cervical lymph node metastasis is a common site of metastasis in the lymphatic pathway, and cancer foci in several parts of the body may have cervical lymph node metastasis. When cervical lymph node metastasis occurs, the metastatic lymph nodes are commonly enlarged and hard, and it is usually easy for multiple metastatic lymph nodes to be fused together, and the mobility of the enlarged lymph nodes is poor. Cervical lymph node metastasis can be treated by lymph node dissection surgery, local radiotherapy, systemic chemotherapy, targeted drug therapy and other treatment modalities. Once discovered, it is necessary to consult the hospital as soon as possible and be given standardized diagnosis and treatment by the doctor to avoid delaying the condition.
