The symptom of constant bowel movement with diarrhea may not necessarily be caused by bowel cancer, but may be caused by benign intestinal diseases or psychological factors. The main clinical symptoms of bowel cancer are changes in bowel habits, such as increased frequency of bowel movements, diarrhea, constipation, and possibly alternating diarrhea and constipation, and often black stools and bloody stools. In addition, patients with bowel cancer may also experience abdominal pain, bloating, loss of appetite, nausea, vomiting, emaciation, anemia, etc. If there is indeed intestinal disease, the doctor will routinely take biopsies for pathological biopsy to help clarify whether the lesion is benign or malignant. For malignant tumors of the intestine, surgery is required, and radiotherapy may be added if necessary. In case of benign intestinal diseases, regular treatment should be given under the guidance of a specialist.
