Question
A three-year-old child has developed a gradually enlarging lump behind the ear and neck, about the size of a bean, without any pain. The parents are concerned about the cause of this lump and the measures to be taken.
Answer
The lump appearing on the neck could be a lymph node or a subcutaneous lipoma. If there is no fever, pain, or adhesion to surrounding tissues, the condition may not be severe. It is recommended to undergo an ultrasound examination or tissue biopsy for confirmation. Lipomas are usually located under the skin, painless and itchy, and can be felt as a bump when touched. Heat compresses with a warm towel can promote absorption, and Chinese medicine treatment is considered, usually due to poor regional blood circulation. It is advised to go to the hospital for a detailed examination.
