What causes moles on the skin

There are many kinds of moles, both congenital and acquired, pigmented moles and sebaceous moles. Some moles are well positioned and are called beauty moles, but there are also many moles that are located in locations that seriously destroy the beauty. Don't worry about that, as you can remove them with laser. So what are the reasons for moles on the skin? Is it possible to prevent moles by understanding the causes? Let me explain the relevant knowledge in detail below.

Overview

Moles can be divided into broad and narrow meanings. The broad meaning includes various congenital and acquired melanocytic nevi, sebaceous nevi, etc. The term "mole" in medicine is used in a narrow sense, also known as nevus cell nevus, pigmented nevus, melanocytic nevus or common acquired melanocytic nevus, and does not include congenital melanocytic nevus. Mole is the most common benign skin tumor in humans. It is a skin manifestation caused by an increase in melanocytes in the epidermis and dermis. Depending on the location of nevus cells in the skin, they can be divided into junctional nevus, mixed nevus and intradermal nevus. Flat lesions suggest junctional nevi, slightly elevated lesions are mostly compound nevi, while papillomatous lesions and almost all hemispherical and pedunculated lesions are intradermal nevi.

Causes

It can be caused by many reasons and there is no definitive answer yet. It is generally believed that the occurrence of moles is related to genetic factors and environmental factors, mainly ultraviolet rays.

complication

May be complicated by infection. Most grow slowly or remain unchanged for many years, but spontaneous degeneration rarely occurs. Some types of moles may turn into malignant ones, thus endangering life.

No treatment is usually required. Junctional nevus and compound nevus occurring on the palms and soles, waist, armpits, groin and other areas prone to friction should be surgically removed when the following conditions occur: ① sudden increase in size; ② blackening or mottled color; ③ erosion, ulceration, bleeding or swelling on the surface; ④ conscious pain or itching; ⑤

Satellite lesions appear around it. Laser treatment is also possible.
