Abstract:

Colorectal cancer is one of the most common malignancies globally. This article reviews global, Chinese, and American colorectal cancer statistics and literature, summarizes the current epidemiological status, temporal trends, risk factors, and screening status worldwide, in China, and the United States, and compares the differences between China, the United States, and the world. Currently, the burden of colorectal cancer remains significant worldwide. Although the incidence of colorectal cancer in China is lower than in developed countries like the United States, it is steadily increasing. Due to the high prevalence of early screening for colorectal cancer, developed countries like the United States have seen a downward trend in both incidence and mortality rates. In contrast, developing countries like China have seen a rise in incidence rates annually, indicating the need to further expand colorectal cancer screening to reduce both incidence and mortality rates.
