Don't panic, this article will help you answer your questions~

Lymph nodes are important immune organs and defense systems in the human body

It is a "battle guard"

Guarding our physical health

At the same time, it is also an "alarm device"

The human body usually has 500~600 lymph nodes, all over the body, under normal circumstances, the lymph nodes are spherical or ellipsoidal, with a diameter of 0.2~0.5cm, smooth surface, soft texture, no tenderness, no adhesion with the surrounding tissues, mainly distributed in the neck, armpits, mesentery, inguinal area and other parts, and the superficial parts can occasionally touch 1~2. 

Why do lymph nodes enlarge?

infection

The most common reason is that when the body is invaded by pathogens such as gram-positive cocci, Epstein-Barr virus, Mycobacterium tuberculosis, etc., the lymph nodes will exert their immune function, and a certain degree of swelling will occur, and fever, increased skin temperature and tenderness around the lymph nodes may occur.

Immune diseases

Such as Kawasaki disease, rheumatoid arthritis, systemic lupus erythematosus, etc., in addition to swollen lymph nodes, it can also be accompanied by fever, rash, joint swelling and pain and other symptoms.

tumor

Such as malignant lymphoma, leukemia, metastatic tumors, etc., most of the lymph nodes at this time are > 2cm in diameter, painless, hard, poor mobility, and multiple occurrences throughout the body, accompanied by fever and abnormal blood images.

Drug reactions

Such as the use of certain antibiotics, anti-epileptic drugs, antidepressants, etc.

Abnormal metabolism of cell proliferation

Such as Langerhans cell histiocytosis, sarcoidosis, Kikuchi disease, etc.

other

Such as lymphatic blockage, vaccination, allergies, etc.

When do I need to see a doctor?

If normal lymph nodes are touched and there is no particular discomfort, they can be observed, and if the following conditions occur, you need to go to the hospital's pediatric internal medicine, pediatric surgery, or hematology-oncology department.

Redness, tenderness, ulceration, increased skin temperature in lymphadenopathy, with or without fever, are considered benign diseases;

Lymph nodes are painless, progressively enlarged, fused, adherent, hard, and multiple throughout the body, accompanied by fever, night sweats, weight loss, etc., and malignant diseases need to be vigilant;

What tests are needed when I see a doctor?

Based on the condition of lymphadenopathy and its accompanying symptoms, we actively search for the cause and perform related examinations.

Routine check-ups:

blood routine, C-reactive protein, procalcitonin and B-ultrasound, etc.;

Special Investigations:

bone marrow aspirate cell morphology, lymph node pathological biopsy and PET-CT, etc.;

Do swollen lymph nodes need treatment?

The key to whether or not a swollen lymphadenopathy needs treatment is to identify the cause, which varies depending on the cause.

If infectious disease is considered, effective anti-infective therapy is required;

If an immune disorder is considered, immunosuppressants or cytotoxic agents are indicated;

If neoplastic disease is considered, chemoradiotherapy, surgery, hematopoietic stem cell transplantation, or multidisciplinary treatment are required.

What do I need to pay attention to after swollen lymph nodes?

Avoid frequent and vigorous pressure on lymph nodes, stay away from harmful chemicals and ionizing radiation, strengthen nursing, pay attention to hygiene, avoid infection, eat reasonably, pay attention to rest, relax moderately, be happy, exercise moderately, and enhance body resistance.

Most lymphadenopathy in children and adolescents is benign and can last for weeks to months, and most of the original disease will return to normal spontaneously after it has improved, and a small number will be malignant. Swollen lymph nodes are not necessarily a bad thing, I hope parents don't be anxious and face it scientifically.
