rt finds differences in CRC screening explained 42% of the observed disparity in CRC incidence between blacks and whites and 19% of disparity in CRC mortality. Stage specific relative CRC survival differences explained 36% of the disparity in CRC mortality. Together, according to the study, differences in screening and survival explained 54% of disparity in CRC mortality. The authors say equalizing access to care could substantially reduce the racial disparities in CRC burden.

As for the remaining 46% to 58% of the disparity in CRC incidence and mortality, known or unknown lifestyle factors are the most likely candidates for the gap. Those include alcohol, smoking, obesity, and meat consumption, which increase the risk of CRC, as well as physical activity and postmenopausal hormone replacement therapy (in women), which decrease risk.
