MOLES
Also called nevi. Moles are common. Almost every adult has a few moles. Adults who have light skin often have more moles. They may have 10 to 40 moles on their skin. This is normal.
Moles often appear as small, dark brown spots and are caused by clusters of pigmented cells. Moles can also be reddish or flesh colored. They can be flat, raised, or hang from the skin.
Moles generally appear during childhood and adolescence although it is not uncommon to develop new moles as you age. However, some moles may fade or disappear as you age.
