Moles are like opinions -- almost everyone has one. In fact, it's normal to have 10 to 40 moles on your skin by adulthood [source: WebMD]. Moles appear when cells grow in clusters instead of spreading throughout the skin. These cells, called melanocytes, make the pigment that gives skin its color, and they can cause moles to darken during teenage years, after sun exposure or during pregnancy [source: WebMD]. Moles can appear anywhere on your body -- from your face to your feet -- and they're typically harmless. However, some moles can be cancerous.

Most moles are benign, but a dermatologist will be able to remove the mole and test it to determine if it's cancerous [source: Leffell].

There are several mole-removal procedures available; however some are more effective than others.
