necrosis
noun
Did you know?
Cells die naturally after a period of time, but may also die as a result of injuries, infections, or disease. Burns produce necrosis, and the bedsores experienced by immobile or bedridden patients are a form of necrosis. The dreaded condition known as gangrene, in which the dying tissue turns black or green, is another form. When untreated, the dying cells release substances that lead to the death of surrounding cells, so untreated necrosis can lead to death. Treatment usually requires the removal of the necrotic tissue, and in severe cases can even involve amputating a limb.
