There is no optimal method for mole spotting. Mole spotting can be done by physical therapy, surgery and other methods. 1. Physical treatment: small diameter, benign pigmented nevus can choose laser treatment and other physical treatment methods, which can utilize the heat energy of laser to remove the local pigment and achieve the purpose of removing nevus. 2. Surgery: Nevi with large diameter and suspected of malignancy can be surgically removed and histopathological examination can be perfected for clear diagnosis. If the nevus cannot be removed directly, free skin grafting, local transfer flap and other surgical treatments can be used, which can try to keep the local aesthetics as much as possible. If patients want to spot moles, it is recommended to go to regular hospitals for consultation and remove moles under the operation of professional doctors.
