Lymph node enlargement after lung nodule surgery is related to abnormal tissue conditions, and the causes of the corresponding conditions include inflammation, immune system abnormality, and tumor.
1. Inflammation: Inflammatory changes may be induced after surgery, which may cause lymphatic tissue proliferation to kill pathogens and further lead to lymph node enlargement.
2. Immune system abnormality: changes in the immune system after surgery may cause reactive lymph node hyperplasia, further leading to lymph node enlargement.
3. Tumor: if the nodule is a malignant tumor, the recurrence of cancer metastasis in the lymph nodes after surgery will also cause lymph node enlargement.
If lymph node enlargement occurs after lung nodule surgery and the lesion continues to aggravate, it is necessary to consult a doctor in time for examination, and after confirming the diagnosis of the disease, carry out standardized treatment under the guidance of the clinician to avoid the delay of the disease.
