Colorectal cancer has become the leading cause of cancer death in men under 50 in the US, highlighting a critical need to reassess cancer risk factors. A perspective by Shi, Cao, and their colleagues analyzes rising early-onset cancers across 42 countries, with significant incidence increases. It raises concerns about existing research frameworks that inadequately capture environmental and behavioral exposures from early life. The authors advocate for improved data systems and methodologies to better understand and prevent these cancers, emphasizing the need for an enhanced epidemiologic approach.
