Moles are skin tumors formed by the aggregation of melanocytes. Moles can be removed, but mole removal has certain adverse consequences, so patients should be prepared for the procedure before considering it. Clinically, if the mole itself has not deteriorated significantly, it is not recommended to remove the mole easily, because the mole removal may lead to local skin infection, and may also lead to scar tissue or pigmentation. For patients with moles on the face, this can further lead to new cosmetic needs, which can be a burden in terms of money and energy. Some patients may experience recurrence after mole spotting, so mole spotting has certain risks.
