Moles (i.e. pigmented nevi) can be removed by physical or surgical methods, which should be chosen according to individual circumstances and medical advice.
1. Physical methods: including electrocautery, freezing, laser treatment, etc., which are generally suitable for removing pigmented nevus with small area (diameter <0.6cm) and no tendency of malignant transformation.
2. Surgical methods: i.e. to remove the nevus locally or even part of the healthy skin around it through single or multiple surgeries, which is generally suitable for removing nevus with large area (diameter ≥0.6cm) or suspected of malignant tendency.
However, it should be noted that the specific efficacy of different methods may vary depending on the timing of treatment, individual physique and compliance, etc. In addition, nevi that have been comprehensively assessed to have a low risk of malignant transformation can also be left unremoved for the time being for further observation.
Therefore, people with pigmented nevi should assess the risk and necessity of removing them under the guidance of a professional doctor, and if they really need to remove them, they should go to a professional medical institution for treatment. Do not blindly dispose of moles on your own to avoid improper intervention and adverse consequences.
