Normal bowel movement with a sense of urgency and a feeling of anal swelling is not necessarily bowel cancer, but also may be sinusitis, enteritis and other possibilities. 1. Sinusitis: acute and chronic inflammation of anal valve and sinus, inflammation stimulates the nerves near dentate line, which can lead to anal swelling and feeling of incomplete stool. 2. Enteritis: congestion, edema and even ulceration of intestinal mucosa can lead to rectal irritation, anal distension and obvious urge to have stool. 3. Intestinal cancer: malignant tumor of intestinal tract is eroded and ulcerated, which can lead to local irritation and symptoms, with the sensation of dyspareunia and anus falling, which can be accompanied by dark-red blood in the stool. In daily life, we should develop good living and dietary habits, such as light diet, less spicy and stimulating greasy food, no alcohol, moderate exercise, enhance resistance, and keep the bowel movement smooth. When there is anal distension, the feeling of having a bowel movement, you need to go to the hospital in time for anoscopy, enteroscopy and other related examinations, to further clarify the diagnosis, and to be appropriate treatment, so as to avoid delaying the condition.
