Generally speaking, moles on the face or other parts of the body are mostly benign, and they can "live in peace" with their owners without any treatment. But some moles need to be treated. The experts from Hefei Plastic Surgery Hospital will tell you. 1, too many moles: the size of moles can sometimes predict whether it will cause trouble in the future. Studies have shown that larger moles are more likely to become malignant than smaller moles (except giant moles). 2, easy to rub: moles that grow in easy-to-rub parts have a higher chance of turning into malignant moles. For example, pigmented nevus that grows on the hands and feet, neck, armpit, chest, head, back, genitals and other easily worn parts has a high probability of malignant transformation, so it must be observed regularly or removed directly to prevent malignant transformation and metastasis. 3. Exposed moles: Sunlight or ultraviolet rays may increase the chances of moles changing, so it is best to remove moles in areas that have been exposed for a long time. 4. long limbs: long soles are prone to melanoma. According to medical statistics, moles at the ends of limbs are the same as moles under fingers or nails, so special attention should be paid. Most malignant melanoma in the East occurs in hands and feet. Therefore, if you find that the moles on your palms and soles grow abnormally fast, you must seek medical attention as soon as possible. 5, unstable cockroaches: cockroaches that will hurt, itch, and change color. 》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》 》
