Moles are spots on the skin where pigmented cells have clustered together. They typically appear as light to dark brown spots on the skin that are either flat or raised. Most people have benign moles, which are harmless.
Moles that become atypical (called dysplastic nevi) might eventually become melanoma. Melanoma is a form of skin cancer. Moles that change or look atypical need to be evaluated by your doctor or a dermatologist.
