Approximately 150,000 new cases of colorectal cancer were expected for the year 2009 in the United States. Moreover, 49,920 deaths related to colorectal cancer were also predicted for the same year. The age-adjusted cancer death rates related to colorectal cancer have steadily declined over the past 2 decades. This improvement is a direct consequence of advances in prevention and treatment, including colorectal cancer screening, diagnostic tests, surgical technique, adjuvant therapies, and medical support.
