A keloid is a type of benign scar or fibrous growth that occurs after healing from a skin injury or wound. It is characterized by an abnormal and excessive growth of collagen, the protein that helps in wound healing. Keloids typically extend beyond the boundaries of the original injury, forming a raised, thickened, and sometimes irregular mass of tissue on the skin's surface.
The exact cause of keloids is not fully understood, but they are believed to occur when the body overproduces collagen during the healing process. Certain factors may increase the risk of developing keloids, including family history, dark skin, tension on the wound site, and hormonal imbalances.
Keloids can develop anywhere on the body, but they are most commonly found on areas with little underlying fat, such as the chest, shoulders, and earlobes. Although they are not harmful, keloids can cause discomfort, itching, pain, and self-esteem issues due to their appearance.
Treatment options for keloids include corticosteroid injections, silicone sheets or gels, cryotherapy, laser therapy, surgical removal, and radiation therapy. However, keloids have a tendency to recur after treatment, making prevention and managing the condition a crucial aspect of care.
In conclusion, a keloid is an abnormal, raised scar that extends beyond the original injury site. While not harmful, keloids may cause physical discomfort and psychological distress. Managing the condition involves various treatment approaches and prevention strategies.
