Why is this scar so large and raised?
A keloid is a greatly enlarged scar that projects above the skin surface. The skin heals by formation of scar tissue, which at first is often red and somewhat prominent. As the months pass, a scar usually becomes flat. Unfortunately, sometimes scars enlarge to form firm, smooth, hard growths called keloids. Some people interchange the term scar with keloid. Keloids are generally larger and more spread out than a scar. Notice the chins of actor, Harrison Ford (Raiders of the Lost Ark) and Gary Cooper (High Noon). They have a prominent scar at their submental crease.

Will these form on any part of the body?
Keloids, or scars, may form on any part of the body, although the upper chest and upper back are especially prone to keloid and scar formation.

How do I treat keloids and scars?
There is no satisfactory treatment for keloids. The best treatment is to inject a long-acting cortisone into the keloid or scar once a month. After several injections with cortisone, the keloid usually becomes less noticeable and flattens in three to six months time. Other cocktail injections are also available which may be beneficial. A new treatment for keloids is to apply a silicone gel preparation over the keloid scar for 12-24 hours each day.

New studies have shown that Laser treatment and microdermabrasion may also be beneficial in reducing the size and appearance of scars and keloids.
