Necrosis refers to cell death caused by external factors such as injury, infection or toxin exposure. Apoptosis, on the other hand, is a controlled process of programmed cell death that occurs naturally as part of development, tissue renewal or as a response to stress. The essential difference between the two types of cell death is that apoptosis is a regulated process, whereas necrosis is an unregulated process.
