Worldwide, there are more than 10 million new cancer cases per year, and cancer is the cause of approximately 12% of all deaths (Silvera Rohan, 2007).

Whether it is from damage or aging, cells eventually die and new cells take their place. However, when cancer develops, this systematic process becomes disrupted. As cells become more and more abnormal, old or damaged cells live when they should die, and new cells form when they are not needed (Doll Peto, 1981). These new cells are able to divide without stopping which can eventually lead to abnormal growths called tumors. Many cancers form tumors.
