How a Scar Tissue Forms
A scar is the remnant or mark left on the body or skin from the repair of a wound. This wound could be the result of a burn, a trauma or a surgical incision. A scar develops because when the body attempts to replicate the tissue surrounding the scar, it tries to blend in the new tissue with the older tissue. The replacement tissue can be considered a “universal” type of tissue that is later converted into the tissue type that surrounds the wound. Although the body does a great job matching this tissue, it is not perfect, and that is why a scar is sometimes visible.
What Happens When Good Healing Goes Bad?
There is no question that the body’s innate sense of wound detection and repair capability is amazing. From perfectly timing the dispatch of hundreds of different kinds of cells necessary for wound repair to knowing exactly how much of each cell is necessary, repair of even the smallest wound is no small feat. Nonetheless, what happens when the healing process goes away?
Different Types of Wound
Some wounds are complicated by contamination with bacteria. Some wounds are complex and require surgical correction. Some wounds require a multistep approach to repair. Regardless of the simplicity or complexity, given the multiple steps required for a body to heal a wound, it is possible that one or more of those steps won’t go according to plan. Our genes provide our bodies with a roadmap of how to rebuild our cells. Sometimes those genes are damaged, impairing our capability for repair. Other times, the same genes that provide information for repair contain the wrong instructions, which can cause things to go wrong in the wound-healing process. This kind of disorder in the healing process is more common than you might think.
One such disorder often experienced by people is called a “keloid.” A keloid, by definition, is an irregular development (in quantity or quality) of fibrous tissue at the site of an injury or scar. Although not harmful, keloids can have an unsightly appearance. Essentially an overgrowth of scar tissue, they are typically seen in response to skin injury and wounds on the surface of the skin. Although surgical scars may heal well, keloids may exaggerate the appearance of the healed wound.
