A skin tag is a small flap of flesh-colored or slightly darker tissue that hangs off the skin by a connecting stalk. Usually found on the neck, chest, back, armpits, under the breasts, or in the groin area, skin tags are not dangerous and usually don't cause pain unless they become irritated by clothing or nearby skin rubbing against them. A doctor can remove a skin tag by cutting, freezing, or burning it off.
