Moles are benign skin tumors formed by the aggregation of melanocytes, and moles do not become malignant, so they can be left alone on the skin and only need to be closely observed. If a mole is accidentally picked off, the first thing that can happen to the patient is the risk of skin infection, because the patient is not able to do a more professional wound management, such as inadvertently touching water or getting dirty things, which will probably lead to skin infection. Other patients have compulsive psychology, so they will repeatedly deduct the mole, which repeatedly brings inflammatory stimulation to the mole, and may indeed lead to malignant change of the mole, and there are similar cases in the clinic, so the mole does not need special treatment.
