Warts are skin growths that grow on any part of the body, including the face, fingers and groin. They have a rough surface on which tiny, dark dots can often be seen. On pressure areas like the palms or the soles, they appear flat. Warts on the sole grow inward from the pressure of standing and walking and are often painful. Warts are caused by a virus, and are otherwise harmless. However, they are contagious, and may spread from one part of the body to another or to other people.
As warts can be a nuisance, dermatologists offer treatments such as minor surgery, electrosurgery, laser, freezing with liquid nitrogen or using special chemicals to remove them.
