Keloid is a type of scar tissue that forms in people who have experienced injury or surgery. There are a few synonyms for the word keloid that can be used to describe this type of scarring. One synonym is hypertrophic scar, which is also a raised, thickened scar that is caused by an overproduction of collagen during the healing process. Another synonym is cheloid scar, which is often used interchangeably with keloid scar. Other synonyms include cicatrix, injury, wound, and scar tissue, which can all be used to describe the physical manifestation of the healing process. Whatever term is used, it is important to keep in mind that keloids can be painful and distressing for those who experience them, and treatment options should be explored to help manage symptoms.
