Introduction of Cancer

Cancer has become a challenge that faces the entire world population. According to the World Health Organization (2004), cancer is the main leading cause of death in economically developed and developing countries respectively. Specifically, American Cancer Society (2012) declares that about 1,638,910 new cancer cases are estimated to be diagnosed and 577,190 people tend to die from it in the United States during 2012.

Moreover, the probable survivability for all cancers cases between 2001 and 2007 is only 67 percent. Compared with former years, a higher percentage of people diagnosed with cancer are less cured. New Jersey Department of Health and Senior Services also estimates that today around four out of every ten people diagnosed with cancer will survive for more than five years.
