Aim: Far less is known about colorectal cancer (CRC) incidence in individuals under the age of 50. This study examined CRC incidence in order to better understand the changing CRC population. Methods: This study analyzed 39,525 CRC cases from the Colorado Central Cancer Registry from 1992 through 2013. Age-adjusted incidence, observed and relative 5-year survival, and estimated annual percentage change was analyzed. Results: Age-adjusted rates averaging 1.7% per year were observed in the under-50 population, while falling on average 4.3% per year (p < 0.05) in the over-50 population. Average-adjusted incidence rose in males under 50 by 2.7% per year (p < 0.05). Conclusion: The absolute incidence of CRC continues to fall in Colorado, however incidence is rising in individuals under 50, particularly males.
