If a child has a lump on the back of his head and it can move, parents may be very worried. This is usually a lump on the back of the head lymph nodes, which is a common symptom among children.

Don't worry too much

Some rare diseases such as lymphadenopathy and lymph node metastasis of malignant tumors can cause swollen lymph nodes, but they are very rare in children of this age. There is no obvious tenderness when the lymph nodes are swollen due to cervical tuberculosis; however, cervical tuberculosis is often characterized by the enlargement of multiple lymph nodes in the neck, often in a beaded shape. In children, this is often part of systemic tuberculosis and should be treated with anti-tuberculosis drugs. The lymph nodes of lymphoma are often hard, tender, and have poor mobility, and are often accompanied by anemia, low fever, etc. Lymphocytic leukemia may cause enlarged lymph nodes throughout the body in addition to enlarged lymph nodes in the head and neck.

Lymph nodes are distributed throughout the body and are part of the immune system.

It also collects and filters the local lymph fluid. Normal lymph nodes are 2 to 3 mm in size, and superficial lymph nodes are easy to touch. However, enlarged lymph nodes are just a symptom and do not indicate a certain disease. Normally, they are not tender, can move, and some can last for a long time without shrinking. Mild enlarged lymph nodes are mostly single or scattered, soft, non-tender, non-adhesive, and not accompanied by other symptoms. They do not need to be treated for the time being, but their changes must be closely observed. If the lymph nodes continue to grow or adhere in clusters, especially if they adhere to surrounding tissues, such as the armpits and groin, and if there are also swollen lymph nodes in other parts of the body, and if there are other symptoms such as fever, anemia, and weight loss, you should go to the hospital immediately for relevant examinations or even a lymph node biopsy to avoid delaying diagnosis and treatment.
