Meatballs growing on the head may be lipomas, sebaceous cysts, soft fibrous tumors, etc. They do not necessarily need to be removed immediately, but surgical removal may be an option in case of compression or suspected malignancy. 1. Lipoma grows continuously, and when it is large in size, it may cause compression symptoms, which will bring adverse effects to the patient’s physical health. 2. Sebaceous cysts may grow bigger and bigger and break down, and the secretion will be accompanied by bad odor after discharge, leaving scar after healing. 3. Soft fibroids can gradually increase in size, affecting the quality of life of patients. With the prolongation of the disease, there is a possibility of malignant transformation, which will seriously affect the life of patients. Therefore, it is recommended that people who have meatballs on their heads should go to the hospital in time, clarify the cause of the disease, and follow up or excise the tumor under the guidance of the doctor, so as to avoid the delay of the disease.
