Using high-quality population-based cancer registry data until 2017, this study presents contemporary trends in early-onset colorectal cancer incidence across 50 countries and territories, including 12 additional countries (Argentina, Bahrain, Belarus, Chile, Columbia, Ecuador, France [Martinique], Iceland, Kuwait, the USA [Puerto Rico], Qatar, and Uganda) since the last published report on colorectal cancer incidence trends. The findings show that the rising incidence of early-onset colorectal cancer is no longer limited to high-income countries; it now extends to countries and territories in Latin America and the Caribbean (Argentina, Chile, Costa Rica, Ecuador, Martinique, and Puerto Rico), Asia (Israel, Japan, Thailand, and Türkiye), and eastern Europe (Belarus).
