Enteritis and intestinal cancer are two completely different diseases in nature, and there are many similar manifestations in terms of symptoms, which may even cause misdiagnosis, but there are still differences in symptoms. 1. Enteritis is an infectious disease of the intestinal tract, which is typically characterized by abdominal discomfort or pain, usually with the intention of stool, and after defecation, the symptoms will be relieved, and the stool can be purulent or watery stool, accompanied by nausea, vomiting, fever and other symptoms, and the number of stools can reach dozens of times a day. If vomiting and diarrhea are frequent, it can cause dehydration and acidosis and electrolyte disorder, such as weakness, heartburn, drowsiness and other symptoms, and the course of disease is about 3 days. 2. Bowel cancer is a malignant tumor of intestinal tract, early symptoms are usually blood in stool, indigestion, habitual change of stool, and the symptoms are not relieved after defecation, sometimes mucous-purulent blood stool, mostly on the surface of stool, to the late stage of the disease, due to tumor ulceration and bleeding and toxin absorption, symptoms such as anemia, emaciation, fever, weakness, etc. can appear, and even abdominal masses and other manifestations can appear, and the course of the disease is longer. Through the above introduction, we have a preliminary understanding of enteritis and intestinal cancer, but a clear diagnosis still needs to be made based on clinical symptoms combined with imaging data and pathological results.
