This case-control study of CRC risk factors in adults in Nigeria found CRC risk patterns similar to those observed in high-income populations. These insights offer immediate opportunity to tailor education, prevention, and early detection in the region, especially as economic development leads to lifestyles more similar to high-income populations. These data provide a foundation for prospective research and investigations in other African populations.
