Bowel cancer recurrence is usually not directly related to food, but bowel cancer patients need to pay special attention to their diet. Bowel cancer usually refers to colorectal cancer, accompanied with symptoms such as lumps in the abdomen and anemia, etc. In terms of diet, it is necessary to eat less greasy, spicy and other stimulating foods, and properly consume foods containing fiber. Because when human body consumes greasy food, the grease will be in the small intestine, which will stimulate the secretion of bile acid and cause the high content of bile acid in the intestines, which will form carcinogenic substances and promote the growth of cancer cells, and may cause the recurrence of intestinal cancer, so patients with intestinal cancer should reduce the intake of grease. Appropriate consumption of food containing fiber can help the peristaltic function of intestines to keep normal, which can increase the volume of feces in the rectum and reduce the residence time, because the feces in the colon will increase the activity of bacteria and produce carcinogenic substances, so patients can consume food containing fiber appropriately. Bowel cancer patients have different degrees of illness, they should eat reasonably under the guidance of clinicians and follow the doctor’s instructions to regulate, which is conducive to the recovery of their condition.
