Many people have moles in various shapes, sizes, and quantities. Moles are simply a concentration of cells that overproduce melanin, or pigment. The appearance of moles depends primarily on your genetic background and the amount of sun exposure you’ve experienced throughout your life.
Some people feel that they have moles that are unsightly or bothersome and so choose to have them removed. Other times moles are an indicator a more serious issue, such as melanoma, and their removal is necessary. Always watch your moles for any changes, especially rapid changes, and watch for strange colorations, raised and/or oddly shaped moles.
