Which parts of our body need to be alert and given high priority for moles? What kind of moles need to see a doctor so that he or she can determine whether they need to be treated? Clinically, we find that Asian pigmented moles that turn into melanoma are mainly of the limb type. In other words, these moles grow on the ends of our limbs, such as the palms of our hands, the backs of our hands, the palms of our feet, and the backs of our feet, and we must pay attention to these areas and pay high attention to them. If these moles suddenly increase in size within a short period of time, and some satellite moles appear around them. If these moles suddenly increase in size within a short period of time, and if there is even some obvious pain, breakage, or bleeding, you should seek surgical treatment from a dermatologist in a timely manner. The photoelectric treatment is not applicable here, but only for simple pigmented nevus. The diameter of pigmented nevus should be less than three millimeters before we can perform photoelectric treatment. As long as the pigmented nevus exceeds three millimeters, in some special parts of the skin, or even if we suspect that it has the tendency of malignant transformation, we recommend patients to undergo surgery. Since we have talked about the harm of moles, where to start to remove “moles” when they are not old? In fact, it is possible for an adult with independent financial ability to have more than one. Let’s focus on the younger children. Because of the child’s age, she will not have the subjective intention to get rid of moles, because the child’s aesthetics is still immature and she will not feel that moles affect her appearance. Generally, it is only when parents find out that their children’s moles will have some influence on them that they will take them to a beauty clinic. Combined with the process of removing moles for children in the past, I think that children should not be too young to remove moles, or at least they should be able to communicate with the doctor before coming to remove moles. Otherwise, the child is too young to cooperate and some violent pressure has to be applied during the whole treatment process, otherwise it is difficult to fix her on our treatment bed. Therefore, I think that children need to be able to communicate with parents and doctors after they are one or two years old before they undergo mole removal treatment.
