A mole is a cluster of skin cells -- usually brown or black -- that can appear anywhere on your body. They usually show up before age 20. Most are benign, meaning they’re not cancerous.
See your doctor if a mole appears later in your life, or if it starts to change size, color, or shape. If it has cancer cells, the doctor will want to remove it right away. Afterward, you’ll need to watch the area in case it grows back.
You can have a mole removed if you don’t like the way it looks or feels. It can be a good idea if it gets in your way, such as when you shave or dress.
