肠镜检查守护肠道健康

Core Viewpoint - The article emphasizes the importance of regular colonoscopy screenings for colorectal cancer, particularly for high-risk groups, to enhance early detection and treatment outcomes [1][2][3]. Group 1: Importance of Screening - The city conducts annual colorectal cancer screenings for residents aged 40 to 74, recommending high-risk individuals to undergo full colonoscopy examinations at designated medical institutions [1]. - Early detection of colorectal cancer significantly increases the 5-year survival rate to over 90%, compared to less than 10% for late-stage diagnoses [2]. Group 2: Prevention Strategies - Colorectal cancer typically develops through a process from polyps to adenomas to cancer, which can take 5 to 10 years; full colonoscopy can identify and remove polyps, preventing cancer development [3]. - Regular full colonoscopy screenings are recognized as the most effective method for preventing colorectal cancer by enabling early detection and removal of precancerous lesions [3]. Group 3: Clarifying Symptoms - Various gastrointestinal symptoms such as bleeding, diarrhea, constipation, and abdominal pain can stem from multiple causes, making accurate diagnosis challenging; full colonoscopy allows for clear observation of the colorectal mucosa to determine the underlying cause [4]. Group 4: Targeting High-Risk Groups - The risk of developing colorectal cancer is significantly higher in individuals over 40, those with a family history of colorectal cancer, or those with a history of polyps or inflammatory bowel disease; regular screenings can help monitor and mitigate these risks [5]. - It is recommended that the general population begin their first colonoscopy at age 45, while high-risk individuals should start as early as 40 or even younger, with follow-up frequency adjusted based on results [5].
