Chronic bowel movements are not necessarily bowel cancer. Unshapable stools, that is, thin stools, can be caused by a variety of reasons, such as chronic enteritis, malabsorption, malnutrition, or malignant tumors of the intestinal tract, etc. Therefore, long-term unshapable stools can be seen in a variety of situations, and it is not necessarily intestinal cancer. How to judge? If there is long-term stool irregularity, especially for people over 40 years old or with family history of tumor, it is better to improve the colonoscopy examination to assist the diagnosis, to see what kind of disease is the cause of this situation.
