Question

My child is almost 3 years old, and I noticed a small bump behind his ear and neck when he was just a few months old. It has gradually grown to the size of a kidney bean and is now clearly visible. He says it doesn’t hurt, but I’m still worried. What could be the cause of this? What should I do?

Answer

The neck mass could be a lymph node or a subcutaneous lipoma. If there’s no fever, pain, or adhesion, the issue should not be serious. If you’re still concerned, you can undergo an ultrasound or tissue biopsy for a better look. Lipomas are typically located beneath the skin, painless and itchy, with a nodular texture. A warm compress can be applied to promote absorption. Traditional Chinese medicine can also be used for adjustment, mainly due to poor regional blood circulation. It’s advisable to have a medical check-up at the hospital.
