Detailed explanation-1: -Sometimes death is necessary-as a fetus develops, cell death helps sculpt tissue into its correct form. Sometimes it’s protective-during an infection, cell death might save the healthy cells from disease. But too much or unregulated cell death can quickly become problematic.

Detailed explanation-2: -Apoptosis removes cells during development. It also eliminates pre-cancerous and virus-infected cells, although “successful” cancer cells manage to escape apoptosis so they can continue dividing. Apoptosis maintains the balance of cells in the human body and is particularly important in the immune system.

Detailed explanation-3: -Cell death is an important process in the body. It removes cells in situations including: When cells are not needed, such as during certain stages of development. To create a structure in the body, for example, the outer layer of the skin is made of dead cells.

Detailed explanation-4: -(PROH-gramd sel deth) A type of cell death in which a series of molecular steps in a cell lead to its death. This is one method the body uses to get rid of unneeded or abnormal cells. The process of programmed cell death may be blocked in cancer cells. Also called apoptosis.
