Cancer is a chronic consumptive disease, coupled with the effects of surgical treatment, chemotherapy and radiotherapy, malnutrition is common in tumor patients. Therefore, how to increase nutrition and reasonable diet is very important for patients' recovery. Some patients worry that eating too well will promote the growth of cancer cells because cancer cells will take energy "savagely", and to promote the apoptosis of cancer cells, it is necessary to limit the nutritional intake, but in fact, this is not based on scientific evidence. Good nutrition can enhance the immune function of patients, resulting in better quality of life and longer survival time. As long as the food is harmless to normal people, cancer patients can eat it.
