Vedclass · Answer

(C) Cancer is characterized by the uncontrolled and abnormal division of cells due to the breakdown of regulatory mechanisms in the cell cycle.Normal cells exhibit a property called contact inhibition,which prevents them from growing uncontrollably when they come into contact with other cells.Cancer cells lose this property of contact inhibition,leading to continuous,rapid,and uncontrolled cell division (mitosis).Meiosis is a reductional division that occurs only in germ cells,not in somatic cells where cancer typically originates.Therefore,cancer is caused by uncontrolled mitosis.
