Colon cancer is a common malignant tumor among general surgery gastrointestinal diseases, and its clinical treatment is currently a comprehensive treatment mode mainly based on surgery, which has remarkable effect, but because of the atypical clinical manifestations of most colon cancer, such as indigestion and abdominal distension, it is easy to be ignored by patients. However, due to the atypical clinical manifestations of most colon cancers, such as dyspepsia and abdominal distension, they are easily ignored by patients. In clinical work, we have encountered liver metastasis, lung metastasis, systemic multiple metastasis of colon cancer, and malignant intestinal obstruction with abdominal hypertension at the first consultation, which is really saddening, and the incidence is getting younger and younger. Surgeons are not afraid of limited liver metastasis, limited lung metastasis, but are most afraid of extensive abdominal metastasis, multiple diffuse liver metastasis and diffuse lung metastasis, which will lose the chance of radical surgery, and then more chemotherapy and more expensive targeted therapy will have little effect. For early stage I and II colon cancer, surgical treatment without high-risk factors is excellent, while the treatment effect and prognosis of stage III and IV colon cancer are worse than those of stage I and II. Most of colon cancers are slow malignant transformation of colon adenoma or circumferential growth, most of them are found only when intestinal obstruction or tumor ulceration and bleeding occurs, most of them are middle and late stage tumors, the treatment effect is not ideal and the best treatment time has been missed. Early detection, early diagnosis and early treatment are the best means and methods for colon cancer treatment. Colorectal cancer evolves from cell to cancer, from adenoma to cancer generally takes 10-15 years, and from cancer to pericyclic growth with intestinal obstruction generally takes 1-2 years. Therefore, it is especially important to change the concept of health and strengthen health management. For high-risk groups whose immediate family members have a history of colon cancer, it is recommended to check colonoscopy once a year after the age of 35, and to check carcinoembryonic antigen, a tumor marker for colorectal cancer, once a year. For the general population, it is recommended to check colonoscopy once every year to 2 years after 35 years old, and check carcinoembryonic antigen and methemoglobin, CA199 once. The best way to treat colon cancer, I think, is early detection and early intervention, so health checkup and health consultation will certainly become an important means of health management, which is also in line with the traditional treatment concept of China, prevention-oriented and combined with prevention and treatment. When colon cancer is widely metastasized, the surgeon only has the feeling that it is difficult to travel, and the surgeon is at a loss when he looks around.
