In a study analyzing data from 204 countries, researchers found that smoking, high body mass index, and alcohol use contribute significantly to colorectal cancer-related deaths, particularly in regions with low socioeconomic levels. While smoking-related colorectal cancer mortality has decreased in high-income countries, it is projected to rise in lower-income regions through 2030. The study suggests that targeted public health strategies focusing on smoking cessation, alcohol moderation, and BMI reduction are crucial for preventing and detecting colorectal cancer.
