The presence of leaves in stool is not a typical manifestation of bowel cancer, and the probability is that it is not bowel cancer. If there are leaves in the stool, it suggests that the patient may have functional dyspepsia or gastrointestinal diseases, details are as follows: 1. Functional dyspepsia: such as eating too much, too fast, or too fast intestinal peristalsis, which can lead to incomplete digestion and absorption of food, which can be manifested as leaves in feces. 2. Gastrointestinal diseases: such as acute gastroenteritis, bacillary dysentery, pancreatitis, etc., which also lead to the decline of digestive function and the presence of leaves in the feces, which need to be examined, diagnosed and treated in time. Early stage bowel cancer usually has no obvious specific manifestations, and there is no obvious dyspepsia manifestations, and may be due to the influence of the cancer, food in the intestinal memory longer, digestion is more complete, it is unlikely to find the vegetable leaves. For those who are older than 40 years old, have a family history of colon cancer, and have previous colon polyps at high risk of bowel cancer, they should undergo regular colonoscopy screening for early detection, diagnosis, and treatment to achieve the best prognosis.
