Ulcer formation refers to the process of forming a sore or wound on an area of the body. It usually involves the breakdown of the skin or mucous membrane, resulting in an open lesion that can be painful and may take a long time to heal. Ulcers can occur in different parts of the body, such as the stomach (gastric ulcers), mouth (canker sores), or legs (pressure ulcers). They can be caused by various factors, including infections, injuries, poor blood circulation, or certain medical conditions.
