Whether the swollen lymph nodes are serious or not depends on the specific causes of the swollen lymph nodes, and is subject to objective analysis. If the swollen lymph nodes are caused by acute infection in the patient’s body, the patient’s condition is not serious if the source of infection in the patient’s body can be actively controlled to promote the self-absorption and remission of the lymph nodes. If patients with multiple lymph nodes are cancerous nodules caused by malignant tumor invasion in the body, patients with early disease can have the primary lesions removed surgically, and the postoperative combination of chemotherapy and radiotherapy can achieve certain therapeutic effects. If the patient’s tumor is late and the opportunity of surgery is lost, only symptomatic supportive treatment can be taken, the prognosis of patients in this case is worse and the patient’s condition is more serious.
