Cancer biology

A cancer cell is a cell that multiplies uncontrollably. Cancer cells ignore cues to stop dividing, to specialise, to die, or to shed and die. The cancer cells may spread to parts of the body where they don't belong because of their aggressive growth and inability to recognise their own natural boundaries. Cancer develops when abnormal cells quickly multiply and spread throughout the body. Normal body cells develop, divide, and know when to stop developing. They pass away too over time. Cancer cells, in contrast to these healthy cells, simply continue to grow and divide uncontrollably and do not pass away as they should. Cell growth is unrestricted in cancer.
