Question
A three-year-old child was found to have a small bump behind the ear and neck several months ago, which has now grown to the size of a bean, clearly visible, and without any pain. The parents are worried about its cause and how to handle it.
Answer
The neck lump may be a lymph node or a subcutaneous lipoma. If there are no symptoms such as fever, pain, or adhesion, it is usually not a serious concern. It is recommended to undergo a color Doppler ultrasound or tissue biopsy for confirmation. Lipomas are usually located in the subcutaneous tissue, painless and itchy, and have a hard lump when touched. Hot compresses with a warm towel can be used to promote absorption, and Chinese medicine adjustment can be considered. The main cause is poor regional blood circulation. It is advisable to go to the hospital for a detailed examination.
