A tumor on the ear after ear piercing often indicates that the patient may be scarred. Patients are strongly advised not to undergo simple surgical excision, as scars will grow worse after simple surgical excision irritates the local area, and the most severe tumors can grow to be larger than an egg. Nowadays, the common treatment for such typical scars is surgery plus incisional low-dose radiation therapy. Surgery is performed to remove the original scar lump and restore it to a normal or near normal state of the earlobe. The purpose of radiation therapy is to inhibit the overactive proliferation of fibroblasts around the wound and the formation of new scars. Radiation therapy is usually started once a day on the day of surgery and is usually maintained for 5-7 days. If the treatment is not effective, 2-stage radiation therapy can also be administered, i.e., radiation therapy can be administered again in case of scar hyperplasia, with the main purpose of preventing the re-formation of scars. Small earlobe scars can be considered for intra-scar injections with tretinoin, which can also suppress the scars and even soften and make them smaller, but cannot get rid of them completely.
