In the United States, cancer is the most common cause of death in people aged 50 years and older. In 2007, a total of 560 000 cancer deaths were reported, accounting for about 23% of all deaths. It is estimated that about 1.6 million new cancer cases will be diagnosed and 570 000 individuals will die from cancer in 2011. Many of the cancers could be prevented if certain intervention strategies are taken such as controlling of tobacco use, improving dietary habits, increasing physical activity, and reducing obesity. Early detection through cancer screening can reduce cancer mortality, increase survival time, and improve quality of life.
