It is best to surgically remove the nevus nigromaculatus. Although laser can be treated, it has the risk of causing skin cancer. Moreover, skin cancer does not appear during treatment, but may appear several years or more later, which was not clear at that time. If you are unhappy, you can wait for a while before treatment. After all, surgery requires general anesthesia, and the bigger it is, the safer it is. If the mole grows quickly, you have to treat it early. The difference is that the early scar is small, but the risk of operation will be greater, and the later scar will be large, but the operation will be safer. This is a comprehensive choice.
