Bowel cancer generally includes small intestine cancer and large intestine cancer. Surgery requires removal of the intestinal tube and some other surrounding tissues and organs, like small intestine cancer may require pancreatic and duodenal resection, and after surgery, digestion and absorption function will be poor. Pay attention to eating less and more meals, you may need to eat 6-8 meals a day. In addition, you should not eat anything too fast or too hot, and other spicy and stimulating things that are not well digested should not be eaten. In addition, colon cancer and rectal cancer, which are common in colorectal cancer, may have similar dietary requirements as small intestine cancer, but some colorectal cancers can also eat normal diet appropriately with the gradual recovery of diet, but the overall principle is to focus on diet with high nutritional value.
