A keloid is an area of irregular tissue that forms at the site of a scar or injury. Unlike most scars, keloids grow beyond the original injury site, covering more area than the initial wound. Keloids are raised and are often shiny and itchy.
Keloid causes
Keloid and hypertrophic scars are the result of an 'exaggeration' of the normal wound healing process that does not properly 'shut off.' Any trauma to the skin can incite a keloid scar to form. There are some areas of the body (the chest for example) that are more prone to keloids and hypertrophic scars than others. People with a strong history (personal or family) are at a higher risk of keloiding.
Keloid Treatment
Treatment for keloids may include steroid treatment, but often require surgical excision. Resistant keloids may require excision or radiation therapy. Some doctors recommend a multidisciplinary course of treatment including topical treatments, silicone sheeting, aggressive TAC injections, and surgery.
Be sure to discuss your concerns with a qualified surgeon or dermatologist.
Keloid prevention
If you know that you are a poor healer and prone to keloids, you should always notify your physician before underoing a procedure. If you sustain another injury somewhere else or have to have surgery, then your physician can take further precautions to help minimize the appearance of your scar. In some cases, a cosmetic procedure (especially in a highly visible area) may not be recommended.
