Keloids are formed from excessive scar tissue formation at the site of prior skin injury. Keloids have a tendency to extend beyond the area of the original skin injury or wound. The cause of keloid formation, and why some people are prone to it and some are not, is not well known. African-Americans are more prone to develop scars and keloids than other ethnicities. Keloids vary in size and can occur on any part of body. Keloids can occur as a result and subsequent to a variety of injuries to the skin:
Keloids are fairly common in young African-Americans and, in severe forms, can become disabling. Size and location of keloids determine the symptoms and the issues that they can cause. Some keloids are small and cause a cosmetic concern only. Larger keloids, especially when located in a critical part of the body, can interfere with daily life, sleep, or other body functions. Large keloids in the earlobe can interfere with sleep as well as hearing and the ability to discern direction of the sound. Treatments for keloids depend on their location, size and thickness. Surgery has traditionally been counterproductive since removing one scar or keloid can result in formation of another one on the same site.
Successful treatment of keloids requires patience and perseverance. As keloids are chronic skin conditions, their treatment also takes time. Each keloid may require more than one method of treatment to achieve a desirable result. Choice of treatment for a given Keloid will depend on its location, size and thickness.
