Necrosis is a type of cell death that occurs in living tissue, usually as a result of disease, injury, or infection. It is characterized by the uncontrolled breakdown of cellular structures, which can lead to inflammation and tissue damage. Necrosis can be acute or chronic and can result in a range of symptoms, including pain, swelling, and discoloration. Treatment for necrosis may involve removing the dead tissue, cleaning and dressing the wound, and providing supportive care to promote healing. In severe cases, surgical intervention may be necessary to remove the affected tissue and prevent further damage.
