Advances in cancer diagnosis and treatment have increased the number of cancer survivors who live for long periods of time.1 In 2005, there were about 11 million cancer survivors living in the United States. Approximately 23% of these survivors had been diagnosed with breast cancer, 19% with prostate cancer, and 11% with colorectal cancer. Approximately 5% of these 11 million cancer survivors were longer-term survivors that had been diagnosed at least 29 years earlier. According to the 2007 NCI's Cancer Trends Progress Report, the total economic burden of cancer in the United States in 2004 was estimated at $190 billion. Direct medical expenditures, which included cancer screening and treatment, accounted for about$90 billion of the estimated $190 billion total economic burden of cancer. The$100 billion difference included indirect costs such as losses in time and economic productivity resulting from cancer-related illness and death.
