Cells in a state of necrosis swell and explode,pouring their contents into the surrounding region,contaminating the environment in which the other cells reside,causing and triggering an inflammatory response,spreading like a chessboard,advancing as a degrading factor.

Necrosis is a process in which there is a loss of energy (therefore loss of signaling factors),leading to defects in the metabolism consequent to the loss of the ionic gradients(these gradients present on the 2 sides of the plasma cell membrane.)
