Nevus generally refers to pigmented nevus, which is generally caused by congenital genetic inheritance as well as chemical and physical stimulation, and can be removed through general treatment, surgical treatment or physical treatment. 1. General treatment: If the color of the mole in the exposed area is light, the area is small, and there is no abnormal change, it can be covered up by using a covering cream, and generally does not need to take special treatment measures. 2. Surgical treatment: If the mole affects the patient’s aesthetic appearance or has abnormal changes, it can be treated by surgical excision if necessary, but it may leave a certain degree of scarring, and if the scope of the lesion is relatively large, it needs to be excised in stages. 3. Physical therapy: Smaller pigmented moles can also be removed by laser therapy, but not all people are suitable for laser therapy, and need to be selected under the assessment of a professional doctor. If the mole has obvious enlargement, bleeding, infection and other abnormal changes in a short period of time, it is recommended to go to the dermatology department in time and actively take targeted treatment measures to avoid continuous deterioration of the condition, which will cause serious effects.
