Moles are defined as small colored spots on your skin caused by melanocytes. Melanocytes are the cells in your skin that are responsible for producing melanin or the pigment that gives skin its natural color. A mole occurs when melanocytes grow in clusters instead of spreading evenly on the skin.The scientific name for a mole is melanocytic naevi. Moles are naturally darker than the rest of the skin because of the concentration of pigment-carrying cells.

The congenital nevi normally present at birth. On average, they present in about 1% of the populous. The congenital nevi have a high likelihood of developing into melanoma cancer (skin cancer) than any of the moles that appear randomly after birth. Larger congenital nevi are more likely to develop into skin cancer than smaller ones. Needless to say, anyone with this kind of mole should visit the doctor.

Dysplastic Nevi are also known as Atypical Moles. Atypical moles are usually larger than the average size of a mole with unusual characteristics. They are uneven in color with a darker brown middle, and their edges are usually irregular with white borders, reddish borders or black dots all around the edges. The good news is, they are commonly benign. They are largely brought about by genes. However, the more atypical moles you have on your body, the higher the risk of developing melanoma in one of the moles. Dysplastic nevi tend to favor Caucasians.In general, 2-8 percent of Caucasians have them. It is, therefore, imperative for anyone who has atypical moles to fiercely protect their skin from harmful UV rays, watch out for changes in the composition of your moles and visit the doctor for periodic checks.
