According to World Health Organization (WHO) in 2008 7.6 million people died worldwide from cancer, approximately 13% of all deaths and estimated that by 2030 the number will increase to 13.1 million (WHO, 2013). In America 1.2 million people died in 2008, affecting men in prostate, lung, and stomach colorectal, and women in breast, lung, and cervical colorectal (PHO, 2013). In Mexico, according to the International Union Against Cancer (UICC), cancer is the third leading cause of death and estimates that each year 128,000 new cases (Ministry of Health [SSA], Undersecretary for Prevention and Health Promotion detected [SPPS], 2013).
