Symptoms of intestinal cancer metastasis mainly include digestive system symptoms, systemic symptoms and metastatic organ symptoms. 1. Digestive system symptoms: Bowel cancer is one of the common malignant lesions in digestive system, and if metastasis occurs, it means that the patient is in the middle or late stage of the disease. At this time, the cancerous tumor is relatively large, which usually causes the intestinal lumen to be not fluent. Patients may have abdominal pain, abdominal distension, nausea and vomiting. At the same time, the cancer will easily rupture and bleed, which may lead to bloody stools, mucus stools, increased frequency of stools and so on. 2. Systemic symptoms: affected by intestinal cancer lesions, patients may have symptoms such as indigestion, malnutrition, emaciation, low fever and fatigue. These symptoms may be confused with other digestive system lesions. 3. Symptoms of metastatic organs: common metastatic sites of bowel cancer include liver metastasis, lung metastasis, etc., which are carried out through blood pathway, lymphatic pathway and plantation metastasis, etc. If liver metastasis occurs, patients may have symptoms of liver metastasis. If liver metastasis occurs, patients may have pain in liver area, jaundice, itchy skin, ascites and so on. If lung metastasis occurs, patients may experience irritating cough, blood in sputum, difficulty in breathing, chest pain, and so on. No matter what symptoms patients have, they should go to the hospital in time and receive regular treatment under the guidance of doctors.
