Research advances in early screening for colorectal cancer (Review)

Early detection and intervention for colorectal cancer (CRC) play crucial roles in reducing the disease burden. However, existing screening methods remain limited in terms of sensitivity, specificity, and compliance. The present review systematically examines and compares cutting-edge research in the field of early screening for CRC performed in recent years, evaluates mainstream screening technologies from multiple dimensions, and provides a theoretical reference basis for the construction of efficient, accurate and sustainable early CRC screening strategies.
