Lymph nodes are physiologic tissues that will be there for life. If the lymph nodes are enlarged due to a disease, it is possible that the enlargement will last for life. Lymph nodes are normal immune organs that exist for life. If the lymph nodes are enlarged due to a disease, it is not certain whether the enlargement will exist for life. If it is simple lymphadenitis, generally through active treatment after the inflammation subsides, most of the lymph node enlargement phenomenon will subside on its own, and will not exist for life; if it is due to the body’s chronic diseases, involved lymph node enlargement, or lymphoma, lymphatic metastasis of malignant tumors and other reasons for lymph node enlargement, it may be lifelong existence. Physiologic lymph nodes do not need to worry and treatment, if there are abnormalities in the lymph nodes, you should go to the hospital in time.
