Approximately 1,500 people die each day of cancer in the United
States. Worldwide, more than 8 million new cases are diagnosed
each year. In affluent, developed nations such as the United States,
around one out of three people will develop cancer in his or her lifetime.
As deaths from infection and malnutrition become less prevalent in
developing areas of the world, people live longer and cancer incidence
increases to become a leading cause of mortality. Clearly, few people
are left untouched by this disease due either to their own illness or that
of loved ones. This situation leaves us with many questions: What causes
cancer? Can we prevent it? Is there a cure?
