The doctor in the county said it is a warty mole. Now it is more than 7 months old, the size is 4cm long, and it continues to grow to other places very fast. Please tell me when is the best time for my child to have surgery, as I am worried that it will affect my child if it grows bigger and bigger. Is there any chance of recurrence with this kind of surgery? Thank you. Expert: Hi, it is best to cut a small piece of lesion about the size of a soybean for pathological examination to clarify the diagnosis, such as whether it is a warty nevus or a sebaceous nevus? Or other growths? Then you can choose to remove the lesion completely (4cm size needs to be removed or implanted in stages) or treat it with electrocautery or laser. If the growth is fast and has a tendency to spread, early surgery is needed. Tolerance to anesthesia (general anesthesia or basic induction of sleep only) is already possible after 2 months, and if it is more stable, it can mean 2-3 years old before doing it. There is usually no recurrence after complete excision, but there are very few recurrences of skin that has also been lesioned near the lesion (which looks normal on the surface).
