After rectal cancer surgery, the patient is weak and needs to rest for two weeks to recuperate. Other treatments are needed after the operation. Postoperative radiotherapy and chemotherapy combined with some auxiliary drugs, selenium Weikang, contains selenium-enriched malt, vitamin E and β-carotene. It can accelerate the recovery of the body after operation, which is supported by literature. Selenium malt can inhibit the proliferation of cancer cells, affect telomerase activity, induce apoptosis of cancer cells and prevent recurrence and metastasis. The combination of radiotherapy and chemotherapy has synergistic and attenuated effects. Reduce the toxic and side effects of radiotherapy and chemotherapy and improve the therapeutic effect.

Precautions for postoperative diet of colon cancer: 1. During diarrhea, we should pay attention to supplementing nutrition and appropriately reducing the cellulose in the diet, such as leeks, celery and garlic moss. And use a diet with less residue to reduce the mechanical damage that high cellulose content may bring to colon mucosa. 2. Regarding the problem of drinking milk for patients with colitis, it depends on whether diarrhea is aggravated after drinking milk, because patients with ulcerative colitis may be allergic to milk protein. On the other hand, some patients may have diarrhea due to the lack of lactase in the intestine. Therefore, patients with inflammatory bowel disease during diarrhea should carefully ask whether they have a history of milk allergy, and limiting the intake of dairy products sometimes plays a role in stopping diarrhea. 3. Due to diarrhea and bloody stool, eating too little for a long time and malnutrition, patients may have iron deficiency, folic acid deficiency or anemia, and should be supplemented appropriately. Generally, it can be supplemented by oral administration or injection. Patients with long-term diarrhea should pay attention to supplement calcium, magnesium, zinc and other trace elements. 4. Correct the imbalance of water and electrolyte in time: colon cancer patients are prone to dehydration, water and salt metabolism disorder and hypokalemia due to a large number of diarrhea and fever, especially when a large number of hormones are used, which is more likely to lead to hypokalemia, and hypokalemia can induce toxic intestinal dilatation. Therefore, patients should take drugs under the guidance of doctors and pay more attention to the reaction after taking drugs. Outpatients with water-electrolyte imbalance due to the aggravation of illness should be hospitalized in time, so as to replenish water, sodium chloride and potassium salt intravenously in time and correct the imbalance between water and acid-base. 5. Don't eat too much fat, fat
