Apoptosis

Apoptosis is an essential process in which cells self-destruct in response to damage or other forms of stress, allowing organisms to regulate their development and maintain healthy cells. Apoptosis plays a major role in development, defending organisms against viruses, controlling cell growth and protecting against cancer. It has also been used in medical treatments such as chemotherapy to treat tumors and is important for tissue repair. Apoptosis is vital for life and its malfunction can lead to several diseases, including cancer.
