If the surgical wound is mildly hyperplastic, i.e., the hyperplastic granulation tissue is slightly higher than the surface of the skin, there is no need to worry too much about it, it is a normal postoperative reaction, you can locally reduce the activities, put on the scar paste or apply scar cream to inhibit the further growth of the granulation tissue, and at the same time, the local area should not be exposed to the sun, to prevent further proliferation of scarring and pigmentation, which will affect the aesthetics. However, if the wound growth is severe, it is necessary to see the attending physician for treatment, sometimes under local anesthesia to remove the growth tissue, and then suture. If the patient does not want further surgery, he can go to the aesthetic department of a regular hospital and be treated with injections of medication, as well as local placement of radioactive elements in order to shrink the localized hyperplasia.
