The difference between intestinal polyps and intestinal cancer in terms of symptoms is blood in stool and bowel habit. For example, most of the patients with intestinal polyps have insidious onset of disease, and the blood in stool is mostly occult blood, and there is no change in the shape of stool; patients with intestinal cancer have blood in stool, change in bowel habit and change in the shape of stool with the development of the disease. Bowel polyps in the early stage are small in size and have low impact on the intestinal tract, the onset of the disease is mostly hidden, and the conscious symptoms are not obvious, some patients will have occult blood in stool or intermittent small amount of bleeding, diarrhea and mucus stool. Early stage of intestinal cancer patients may have no obvious symptoms, with the progress of the disease, there is blood in stool, the blood is visible to the naked eye, bright red or dark red, and there is a change of defecation habit such as incomplete defecation, constipation, diarrhea, etc., and often accompanied by a change of stool characteristics, the patient is prone to intestinal obstruction, and the patients with advanced stage of intestinal cancer may have anemia, fatigue, shortness of breath, and other symptoms. If patients with intestinal polyps fail to receive regular treatment in time or make regular follow-up after surgery, there is a risk of developing into intestinal cancer. If the above symptoms occur, it is recommended that patients go to the hospital in time, and have regular and reasonable treatment as soon as possible to avoid aggravation of the condition.
