What Are the Factors Underlying Colorectal Cancer Health Disparities?

Abstract

Abstract Black Americans have the highest colorectal cancer incidence and mortality rates of any U.S. racial/ethnic group. Warren Andersen and colleagues report that sociocultural, lifestyle, and healthcare factors did not explain the racial disparity in colorectal cancer incidence, but colorectal cancer screening lessened the disparity. While screening is a cornerstone of colorectal cancer prevention, an improved understanding of etiologic factors may inform additional strategies for primary prevention or risk stratification. As important “established” colorectal cancer risk factors have not been corroborated for Black Americans, this begs the question of what other etiologic factors are important for colorectal cancer development in Black American populations.
