Effect of colonoscopy screening on the risk of colorectal cancer in China: a follow-up study.

ABSTRACT:

Colorectal cancer (CRC) is one of the most common cancers worldwide. Colonoscopy is the gold standard for CRC screening, but its effectiveness in population-based programs requires further evaluation.

Methods
