Almost everyone has a mole. When it needs to be removed because of its aesthetic impact, should I choose surgical removal or laser (liquid nitrogen freezing, etc.) removal? What are the advantages and disadvantages of both? In general, if the diameter of a mole is less than 2.0mm, you can try laser (liquid nitrogen freezing, etc.) removal, but it is difficult to judge the specific boundary of removal during operation, so it is also difficult to guarantee a complete removal, especially when the mole is larger, it is more difficult to judge, and the complete removal may be smaller, generally 70-80% may be removed at one time, of course, there is a certain difference with the level of the doctor, and it is necessary to There is, of course, a certain difference with the level of the doctor, and the need for re-operation or intermediate surgery is possible. This method of removal cannot obtain pathology and ultimately does not know the nature of the specific nevus, there is a possibility of malignancy under laser stimulation, but it is very small. A depressed scar (small pit) will be left. The surgery allows complete excision down to the subcutaneous tissue, and complete excision is generally possible at 99% or more, with the possibility of requiring secondary excision rarely. A linear scar (thin line) will be left, and the thin line is usually less visible than a small pit.
