Introduction
Whether colorectal tumors can be cured depends on the nature of the tumor, the stage of malignant tumors, and the timing of treatment. Benign tumors can mostly be completely cured with standardized treatment. Early-stage malignant colorectal tumors also have a favorable prognosis with active intervention, whereas treatment becomes more challenging in intermediate and advanced stages. When symptoms such as rectal bleeding, changes in bowel habits, or abdominal pain occur, timely medical evaluation via colonoscopy is recommended to determine the nature and stage of the tumor.
大肠肿瘤能否治好取决于肿瘤性质、恶性肿瘤的分期及Treatment时机，良性肿瘤通过规范Treatment多可根治，早期恶性大肠肿瘤经积极干预也能获得较好预后，中晚期则Treatment难度增加。具体分析如下：
大肠肿瘤分为良性与恶性两类。良性肿瘤，如大肠腺瘤、脂肪瘤生长缓慢，不发生转移，通过内镜下切除或Surgery完整移除后，多数Patient可完全治愈，术后定期复查即可，复发风险较低；若良性肿瘤体积小、无明显Symptoms，也可在Doctor评估后选择观察，避免过度Treatment。
恶性大肠肿瘤即结直肠癌，若处于早期，肿瘤局限于肠壁内、未发生淋巴结或远处转移，通过Surgery切除肿瘤及周围受累组织，配合术后必要的辅助Treatment，如化疗、靶向Treatment，部分Patient可达到临床治愈，5年生存率较高；若肿瘤已发展至中晚期，出现淋巴结转移或远处器官转移，Treatment目标则转为控制肿瘤进展、延长生存期、改善Life质量，虽难以完全根治，但规范综合Treatment仍能明显缓解Symptoms、延长生存时间。
出现便血、排便习惯改变、腹痛等Symptoms时，Recommendation及时就医通过肠镜、病理Examination明确肿瘤性质与分期，在Doctor指导下开展Treatment，降低复发风险。
