Early stage of stomach cancer may have no obvious symptoms, and the color of stool may be normal, that is, yellow and fluffy. Stomach cancer is usually caused by living habits, such as irregular diet for a long time, and there may be chronic gastric diseases for lesions, such as atrophic gastritis, intestinal epithelial hyperplasia and other diseases. With the development of the disease, a small amount of blood in stool or other conditions such as black stool may occur, and some other conditions may also produce abnormal color of bowel movement, such as intestinal problems or dietary factors. Early stage of gastric cancer can be treated with surgery, which can remove most of the stomach or radical total gastrectomy, and the effect is relatively good. After surgery, 4~6 courses of adjuvant chemotherapy are usually needed, and if malignant tumors are found, adjuvant radiotherapy can be considered to prevent the occurrence of obstruction of eating. If you find abnormal stools, it is recommended to consult a doctor in time and standardize the treatment and medication under the guidance of a professional doctor, so as not to delay the condition.
