Association between the red blood cell distribution width-to-albumin ratio and risk of colorectal and gastric cancers: a cross-sectional study using NHANES 2005–2018

This study reveals a significant association between RAR and colorectal cancer (CC) risk, indicating that RAR may serve as a valuable biomarker for risk stratification. For individuals with abnormal RAR values, the integration of supplementary screening tools-such as fecal occult blood testing, colonoscopy, or additional biomarkers-could enhance early detection rates for CC. This strategy would allow healthcare providers to more effectively identify high-risk individuals and tailor personalized prevention strategies.
