Early-Onset Colorectal Cancer Risk Factors Explored
A large-scale study identifies demographic and biological risk factors for early-onset colorectal cancer, including sex, ethnicity, and birthweight. Findings suggest that Hispanic individuals and males face higher risks, while maternal birthplace plays a protective role.
Why it matters
Understanding these specific risk factors is crucial for developing targeted screening programs and early intervention strategies for younger populations.
MALE sex and Hispanic ethnicity increase early-onset colorectal cance r risk, while foreign maternal birthplace provides protection. In a large population-based nested case-control study from the California Linkage Study of Early-Onset Cancers, investigators evaluated statewide birth records matched with cancer registry data from 1988 through 2021. The investigation encompassed 1,221 individuals diagnosed with first primary early-onset colorectal cancer between ages 0 and 39 years, along with 61,050 birth-year matched control subjects without cancer diagnoses. Researchers performed multivariable logistic regression to elucidate how demographic, birth, and parental characteristics influence early malignancy.
