ABSTRACT
Despite signi cant advances in the elds of genetics, molecular biology, diagnosis, and treatment, cancer is still the second leading cause of death worldwide (Mathers et al., 2001). According to the recent available information, in the year 2002, excluding the nonmelanoma skin cancers, there were more than 10 million new cases of cancer recorded globally, with nearly 7 million cancer deaths (WCRF/AICR, 2007). Projections are that by the year 2020, these gures will increase to over 16 million new cases, with 10 million deaths. In 2030 there may be more than 20 million new cases of cancer, with 70% of cancer deaths in the low-income countries, which have minimal resources to treat it (WCRF/AICR, 2007; Mackay et al., 2006). All these observations suggest that there is an urgency to work toward educating people on the causes of cancer, its detection, and prevention and also to design interventional strategies that are inexpensive and affordable to the common man (Arora, 2009).
