Although the global burden of colorectal cancer (CRC) has declined from 1990 to 2021, particularly in high-income regions, the incidence rate continues to rise. The increase is more pronounced among individuals aged 50 years and older, who also bear a higher absolute incidence than younger populations. High red meat consumption, high body mass index (BMI), and low calcium intake remain the leading global risk factors for CRC. Effective weight management and the promotion of healthy lifestyles are essential strategies for reducing CRC risk across sexes, while smoking and alcohol control are particularly critical for alleviating the burden among males.
