Colorectal cancer (CRC) is the second leading cause of cancer-related deaths globally. The risk of disease increases with age, as most CRC patients are over 50 years old. Due to the progressive aging of societies in high-income countries, the problem of CRC will increase. This makes the development of new early detection methods and the implementation of effective screening programs crucial. Key areas of focus include raising population awareness about the importance of screening, educating high-risk populations, and improving and developing early diagnostic methods. The primary goal of this review is to provide a concise overview of recent trends and progress in CRC secondary prevention based on available information from clinical trials.
结直肠癌（CRC）是全球癌症相关死亡的第二大原因。该疾病的风险随年龄增长而增加，大多数CRC患者年龄超过50岁。由于高收入国家社会人口逐渐老龄化，CRC问题将日益凸显。这使得开发新的早期检测方法和实施有效的筛查计划变得至关重要。重点关注领域包括提高公众对筛查重要性的认识、教育高风险人群，以及改进和开发早期诊断方法。本综述的主要目的是基于临床试验的现有信息，简要概述CRC二级预防的最新趋势和进展。
