A typical symptom of bowel cancer is blood in stool, which is a danger signal. Patients with such danger signal must be examined as soon as possible, and the more common examination method is colonoscopy, and pathological diagnosis can be made only through pathological diagnosis if tumor is found. Other patients may have dry stools or diarrhea, irregular stools, increased frequency, etc. In short, bowel cancer patients’ stool performance is quite obvious, and it is normal for a normal person to have 1-2 times a day or once every 3 days.
