Many people have moles on their bodies, and while some people don’t think about it, others are worried. Master Li, who is 60 years old this year, recently had some red moles on his body. At first, he didn’t take it seriously, but some people who saw it said that it was a disaster mole and should be removed immediately, while others said it was a lucky mole for the elderly. What exactly is it? The old man was also confused, so he wrote to ask if these moles should be removed. If they should be removed, how should they be removed? Mole, scientific name: melanocytic nevus. It is an aggregation of melanocytes located at the junction of the epidermis and dermis of the skin, which can be higher than the skin surface or flatter than the skin, and varies in size and location. Generally speaking, the chance of malignant change in nevi is still rare. The nature of melanoma is stable, or even no obvious changes throughout life, but if the following conditions occur, it is a sign that malignant change will occur: 1. the lesion increases significantly within a short period of time; 2. the color changes, deepens or pigment loss occurs; 3. hair loss and scabbing occurs; 4. no obvious history of trauma but the surface breaks down and bleeds for a long time; 5. there is local inflammation; 6. itching or painful symptoms occur 7.Pigmentation spots of pinpoint size, called satellite foci, appear immediately around the lesion. These are all undesirable phenomena and should be checked out in hospital as early as possible. Moles like those on the palms and soles of the feet have increased the chance of malignant transformation due to frequent friction and should also be removed as early as possible.
