Firstly, the introduction of malignant melanocytoma in the “Non-Stop II” and then in various health programs has made more and more people anxious about their moles, even to the extent that they can’t sleep at night. In fact, are moles really as scary as time bombs? The answer is of course no. The incidence of malignant melanoma is very low, less than 1 in 100,000 in China, and only a small percentage of them are transformed from moles, which also include congenital giant nevi (animal skin nevi). Although there are no exact statistics on the malignant rate of pigmented moles in the population, with an average of 20 moles on each person, we can see that the chances are much lower again. Therefore, having moles on the body is not a terrible thing, but it is important to care for yourself and perform regular self-examinations to detect abnormal manifestations of the organism. The prognosis of early treatment of malignant melanoma is still very good. The moles in the title are in quotation marks because the “moles” that people talk about are not necessarily real moles. Some of them are malignant melanoma, some are basal cell carcinoma, some are seborrheic keratosis (old wart), etc. As malignant skin tumors, the most typical manifestation is fast development, and if there is a definite increase in size within 1-2 years, you must be alert (pigmented nevi in childhood grow faster and are normal; benign diseases such as seborrheic keratosis are mostly seen in middle-aged and elderly people and can grow faster). It is best to ask an experienced dermatologist to help determine what the diagnosis is and, if necessary, to examine the skin with the help of pathological sections. Most malignant skin tumors are also more likely to bleed (malignant melanoma does not appear in the early stages), and it is also important to seek prompt medical attention if this is the case. If you just have a real mole, what you need to do is to avoid stimulation of the mole, observe it regularly, and seek medical attention if there are any abnormal changes. Whether for aesthetic reasons or for fear of its malignancy, laser or freezing or chemical cautery is not recommended, and surgical removal is recommended.
