Bowel cancer bowel sounds do not necessarily have three pains, and bowel cancer patients usually do not have significant abdominal pain in the early stages. There are generally two types of abdominal pain in bowel cancer patients. 1. Pain can appear when the tumor in the intestinal tract compresses its surrounding tissues, blood vessels and nerves, and this pain is usually persistent, gradually aggravating dull or hidden pain, which can be accompanied by abnormal stool pattern or blood or mucus on the surface of stool. Stool habits may change, alternating between diarrhea and constipation. 2. Tumor causes obstruction of the digestive tract, increased peristaltic responsiveness of the intestines, which can cause intestinal tinnitus, and in severe cases, it can lead to intestinal spasm, causing intestinal colic, which is usually paroxysmal pain, and sometimes the abdominal mass with fixed position can be touched in the abdomen. It is recommended to consider the diagnosis with clinical symptoms, and the only gold standard for the diagnosis of intestinal cancer is still pathological examination. It is recommended to consider colonoscopy, and abnormal hyperplasia foci should be microscopically biopsied to confirm the diagnosis. If there is any discomfort in the abdomen or change in the stool, it is recommended to consult a doctor in time and standardize the treatment under the guidance of a professional doctor, so as to avoid delaying the condition.
