Colorectal cancer screening in high-risk groups is increasing, although current smokers fall behind.

Background: There is limited information about colorectal cancer (CRC) screening trends in high-risk groups, including the black, obese, diabetic, and smoking populations. For this study, the authors evaluated national CRC screening trends in these high-risk groups to provide insights into whether screening resources are being appropriately used.

Methods: This was a nationally representative, population-based study using the Behavioral Risk Factor Surveillance System from the Centers for Disease Control.
