Colorectal incidence and mortality have declined as screenings increase

Colorectal cancer incidence and mortality have declined, while screening has increased across the United States in recent years, according to a report from the Centers for Disease Control.

The report examined data for colon cancer screening between the years 2002—2010, and looked at incidence and mortality rates between 2003 – 2007.

Key findings:

  • From 2002 to 2010, the percentage of persons aged 50 - 75 years who were adequately screened for colorectal cancer increased from 52.3% to 65.4%
  • From 2003 to 2007, CRC incidence declined significantly in 35 states, and mortality declined in 49 states and DC
  • Screening and changes in risk factors each accounted for 50% of the decline in mortality, with the largest declines occurring in states with some of the highest screening rates
