Suggestion: Hello! With the enlargement of tumor, patients with colon cancer will have liver metastasis symptoms such as jaundice, ascites and edema, as well as distant metastasis such as cachexia, rectocele and supraclavicular lymph node enlargement. Due to the differences in physiology, anatomy and pathology, the clinical characteristics of left and right colon cancer are also different. The symptoms of late colon cancer are mainly manifested in the following two aspects: 1, left colon cancer: the intestinal cavity of the left colon is relatively narrow, and the feces are sticky so far. This part is mostly invasive cancer, and the intestinal cavity is often annular narrow, so the symptoms of intestinal obstruction appear earlier in clinic, and some even appear acute obstruction. Poisoning symptoms are mild and appear later. 2. Right colon cancer: The intestinal cavity of the right colon is wide, where the feces are sparse, the blood supply and lymph of the colon are rich, and the absorption capacity is strong. Most cancers are soft cancers, which are prone to ulceration and necrosis, leading to bleeding and infection, so the clinical manifestations are mainly toxic symptoms. However, intestinal obstruction will also occur when the condition gets worse. Patients with advanced colon cancer invade the intestine due to malignant growth of tumor, which leads to intestinal stenosis, obstruction of defecation to varying degrees and reduction of food intake. At this time, we should pay attention to giving patients foods rich in nutrition and low in crude fiber, such as eggs, lean meat, bean products, flour and rice, and young leaf vegetables. And told patients to drink more honey water and eat more bananas and pears, among which honey has the best laxative effect. If it is determined that it is really advanced, the pain of the patient should be reduced as much as possible in the treatment. It is helpful to take some traditional Chinese medicines, such as ginsenoside Rh2, which can inhibit the development of the disease, diminish inflammation and relieve pain, and have a good effect on improving patients' appetite and sleep.
