Development and Causes of Cancer
Cancer is a vast medical condition that affects people all over the world. Currently, it is the core cause of mortality in the western part of the world (Tobias & Hochhauser, 2010). In light with this, Silverstein, Silverstein and Nunn (2006) assert that cancer is not a single disease, but a group of more than hundred diseases that have one basic thing in common. Silverstein, Silverstein and Nunn (2006) still describe cancer as a change that occurs in the body resulting to uncontrolled growth and multiplication of cells.
