There are no special symptoms in the early stages of intestinal tumors. Later, if the following symptoms appear, colon tumors should be considered and intestinal tumor diagnosis and examination should be carried out in time to avoid delays. Symptoms of intestinal tumors: 1. Anemia and cachexia. 2. Changes in bowel movements, such as frequent bowel movements, constipation, blood in the stool, or bloody and mucous stools. 3. Abdominal distension, abdominal pain, or palpable abdominal mass. 4. There are symptoms of intestinal obstruction. The diagnosis of intestinal tumors is mainly based on barium or gas barium double enema and fiber colonoscopy. For rectal tumors, the most simple and practical method is digital rectal examination, or proctoscopy or sigmoidoscopy. CT, MRI and other examinations are very helpful in understanding tumor invasion and finding metastatic lesions. The serum carcinoembryonic antigen (CEA) test is non-specific, but the positive expression of colorectal tumors can be as high as 70%, so it is more suitable for postoperative monitoring of recurrence and metastasis. Timely and effective diagnosis and examination of intestinal tumors will greatly facilitate the treatment of the disease, not only facilitating treatment but also recovery.
