Whether the patient’s multiple lymph nodes in the neck are serious or not should be analyzed objectively based on the size, morphology and nature of the lymph nodes. First, if the volume of lymph nodes in the neck is small, the boundary is clear and the morphology is regular, the possibility of benignity is considered by ultrasound examination, and in this case multiple lymph nodes in the neck will not cause serious effects on the human body. Secondly, if the lymph nodes in the neck are larger in size, accompanied by local nerve and blood vessel compression symptoms, and the lymph nodes are harder in texture, with unclear borders and poor mobility, accompanied by obvious fusion phenomenon, cancerous lymph nodes are highly suspected through ultrasound or CT examination. At this time, the patient’s condition is more serious, so it is necessary to perform lymph node biopsy as soon as possible, clear the primary tumor and perform lymph node dissection as soon as possible, so as to remove the tumor cells in the body as much as possible, and patients with early disease can achieve better treatment effect.
