Definition of Cancer

Cancer is an abnormal growth of cells caused by multiple changes in gene expression leading to dysregulated balance of cell proliferation and cell death and ultimately evolving into a population of cells that can invade tissues and metastasize to distant sites, causing significant morbidity and, if untreated, death of the host.

Cancer is a single word which is used to describe about 200 different diseases affecting organs or systems throughout our bodies. Each form of cancer is unique in terms of its development, possible causes and behaviour.
