What is Apoptosis?


Updated February 17, 2013


Apoptosis refers to the death of a cell resulting from a normal series of genetically programmed events, when a cell is no longer needed.

Apoptosis is a natural process that removes cells that have become old or unhealthy.

Apoptosis is important in understanding cancer, because cancer cells have, in a simplistic sense, developed a way to avoid apoptosis. Newer treatments are being studied that interfere with the cancer cell's ability to avoid apoptosis.
