Keloids can develop following the minor injuries that occur with body piercing. Since this form of physical adornment has become popular, the presence of keloidal scarring is much more prevalent. Since doctors do not understand the precise reasons why some people are more prone to developing keloids, it is impossible to predict whether piercing will lead to keloid formation. Although there are some families that seem prone to forming keloids, for the most part, it's impossible to tell who will develop a keloid. One person might, for instance, develop a keloid in one earlobe after piercing and not in the other. It makes sense, however, for someone who has formed one keloid to avoid any elective surgery or piercing of any body part.
