Metastasis of colon cancer to stomach is not common in clinic. After stomach metastasis, abdominal pain, abdominal distension, nausea and vomiting, weight loss, dyspepsia and other symptoms will appear, and in serious cases, vomiting blood, black stools and intestinal obstruction will appear. Early stage of colon cancer usually has no obvious symptoms, but when the mass is too big or metastasized to the gastrointestinal tract, it will reduce the digestive ability of the stomach and cause indigestion and other symptoms. Colon cancer can metastasize to stomach through gastrocolic ligament and cause related symptoms. At present, early gastric metastasis can be treated by surgery and chemotherapy (such as 5-FU, vincristine, etc.) after surgery, and the specific treatment depends on the actual staging and grading. If you have the above symptoms, you should consult a doctor in time to get a clear diagnosis. If you find gastric metastasis at an early stage, you can under the guidance of a doctor carry out surgical treatment to improve the symptoms, so as to avoid delaying the golden period of treatment.
