If the patient has persistent abdominal pain and bloating, it is mostly considered to be related to constipation, gastroenteritis and other diseases, not necessarily bowel cancer. The onset of bowel cancer is relatively hidden, and there are no specific symptoms in the early stage, which are often manifested as indigestion, fecal occult blood and so on. With the progress of the disease, there may be changes in the character of stool. As there are many reasons for persistent abdominal pain and bloating, patients should first consider digestive system diseases, such as constipation, gastroenteritis, intestinal obstruction, etc. Patients can have enteroscopy, gastroscopy, barium meal examination for differential diagnosis. Once the patient has persistent abdominal pain, bloating and other symptoms, the patient should consult the gastroenterology department to confirm the cause of the disease and give symptomatic treatment. If the diagnosis of intestinal cancer is confirmed, the patient should follow the doctor’s prescription for surgical treatment, and the five-year survival rate is high.
