Keloids

A keloid (say "KEE-loyd") is a scar that grows bigger and wider than the original injury. Keloids most commonly grow on the breastbone, shoulder, upper chest and back, earlobes, and face.

Keloids do not become cancer. But they can be bothersome or painful enough that you seek treatment. Keloids often grow back after treatment.

It's possible to prevent a keloid from forming if you take steps to protect the skin after it is damaged.

Keloids look like firm, raised, hard scars. They grow larger over time. Their colors vary from slightly pink to very dark.

Keloids can rub against your clothes and become irritated, itchy, or painful. When exposed to the sun, they may turn darker than the rest of your skin. The dark color may stay.

There is no sure cure for keloids, but treatment sometimes improves how they look and feel. It is common for keloids to grow back after treatment.

When trying to treat a keloid, your doctor may need to use more than one type of treatment. Based on a keloid's size and location, and how soon it is treated, your doctor may:

• Freeze it. This is called cryotherapy. It is best used for small keloids, such as from acne. Cryotherapy can lighten the skin.
• Inject it with medicine.
  • A corticosteroid is the most commonly used medicine for reducing keloids. It is most likely to work well with cryotherapy or right after surgery.
  • Other medicines may improve keloids. These include verapamil, fluorouracil, bleomycin, and interferon alfa-2b shots. They are not as well studied as corticosteroid shots, but your doctor may recommend trying one. They are most likely to work when used with another treatment.
• Cut it away. Surgery is sometimes used to remove larger keloids. But removing keloids can lead to more keloids. So it's important to treat the area after surgery. Treatment may include laser or medicine injections. You can also:
  • Cover the area with a silicone gel bandage after surgery. You can buy these at most drugstores. Keep the silicone bandage on the skin for 12 to 24 hours a day for 2 to 6 months. Your doctor will tell you when you can stop treatment.
  • Keep pressure on it with a wrap or bandage.

Radiation tends to be reserved as a last option for treating keloids. There is a chance that it can cause cancer.

Your health insurance may cover some keloid treatments, but not others. Your treatment also may not be covered if the insurance company thinks it's being done only to improve how the scar looks (cosmetic reasons).

• Keep wounds clean and dry to prevent infection.
• If you tend to get keloids, cover cuts and other damage to the skin with a silicone gel bandage. Cut the silicone gel slightly bigger than the skin wound. Cover the silicone gel with a bandage or wrap to keep pressure on the cut or other injury.
• If you get keloids, you may want to avoid body piercings, tattoos, or any surgery you do not need. Keloid scarring can happen after these procedures.
