Colorectal cancer is one of the most common malignant tumors. Its complications seriously affect the quality of life and prognosis of patients. The following are related to the common complications of colorectal cancer: 1. Intestinal obstruction: Cause: Colorectal cancer can lead to intestinal stenosis or obstruction, causing obstruction of fecal excretion. Symptoms: abdominal pain, abdominal distension, vomiting, stop of exhaust defecation, etc. Treatment: According to the severity of the disease, surgery, gastrointestinal decompression, enema and other methods can be adopted. 2. Intestinal perforation: Cause: Tumor invasion of the intestinal wall leading to perforation. Symptoms: Sudden severe abdominal pain, accompanied by signs of peritonitis. Treatment: Surgical repair of perforation, while peritoneal irrigation and drainage. 3. Bleeding: Cause: Tumor surface ulcer, erosion or vascular invasion. Symptoms: Positive stool occult blood, black stool, bloody stool, etc. Treatment: hemostasis under endoscope, surgical hemostasis or interventional treatment.4.Infection: Cause: intestinal obstruction, perforation, etc. leading to intestinal bacterial translocation. Symptoms: fever, abdominal pain, diarrhea, etc. Treatment: antibiotics, active drainage of infected foci. 5.Malnutrition: Cause: tumor consumption, anorexia, digestive absorption disorders. Symptoms: weight loss, anemia, fatigue, etc. Treatment: adjust diet, provide nutritional support, and provide enteral or parenteral nutrition if necessary. 6. Liver metastasis: Cause: Colorectal cancer can metastasize to the liver through blood circulation. Symptoms: Liver pain, jaundice, ascites, etc. Treatment: comprehensive treatment such as surgical resection, chemotherapy, and targeted therapy. 7. Lung metastasis: Cause: Colorectal cancer can metastasize to the lungs through blood circulation. Symptoms: cough, hemoptysis, chest pain, etc. Treatment: surgery, chemotherapy, radiotherapy and other comprehensive treatment. For colorectal cancer patients, especially advanced patients, the prevention and treatment of complications is very important. Doctors will formulate personalized treatment plans according to the specific conditions of patients, including surgery, chemotherapy, radiotherapy, targeted therapy, etc., to control tumor progression, alleviate complications and improve quality of life. In addition, patients should pay attention to diet adjustment during treatment, maintain a good attitude and actively cooperate with treatment.

For high-risk groups, such as familial colorectal cancer patients, patients with chronic ulcerative colitis or colon polyps, colonoscopy should be performed regularly to detect and treat colorectal cancer early. In short, complications of colorectal cancer need to be highly valued, and timely diagnosis and treatment are critical to the prognosis of patients. Patients and families should work closely with doctors to develop the best treatment plan.
