Moles are the irregular formation of melanocyte cells that give color to the skin. Human skin has two main layers, the epidermis and the dermis, between which melanocyte cells spread. A layer of fat is seen under the skin.
In the early stages of the formation of the baby in the mother’s womb, the antecedents of melanocyte cells are seen in relation to the nerve cells. They spread to the skin, hair and eyes, which are formed during the later stages of growth.
Thus, during the journey to different parts of the body, some melanocyte cells get trapped inside or under the fat layer of the skin, which are seen as moles. Some moles may be present at birth. Others will come to light later. However, the anterior appearance of the latter may be present at birth, and the moles are usually green, blue, or yellowish-black in color. It is superstitious to think of moles as good luck. In fact, some of these have the potential to become cancerous. Do not lightly discard moles that change color, feel smoky or grow.
