I. Post-operative conditioning Surgery is most likely to damage qi and blood, therefore, preoperative nutrition should be increased as much as possible to benefit qi and blood and enhance physical fitness to create conditions for surgical treatment. Most of the postoperative patients are suffering from deficiency of Qi and Blood, and deficiency of fluid and blood. Therefore, it is advisable for postoperative patients to eat foods with strong tonicity, such as fish, shrimp, mutton, turtle, etc.; choose some iron-rich foods, such as liver of various animals, egg yolk, tomato, spinach, apricot, peach, grape, grapefruit, etc. At the same time, supplemented with ginseng, astragalus, angelica, wolfberry, silver fungus, red dates, cinnamon and other drugs to increase the body’s tolerance, restore physical strength, resistance to disease. Second, chemotherapy before and after conditioning Chemotherapy is one of the common methods for treating malignant tumors and is generally applied to patients who have lost the chance of surgery or relapsed after surgery or radiotherapy. During chemotherapy, chemotherapy drugs, while killing tumor cells, will also cause certain damage to normal cells and produce corresponding and huge toxic side effects. Without nutritional treatment for tumor patients, normal cells, tissues and organs are bound to be damaged. And reasonable diet can prevent and reduce weight loss and malnutrition brought by treatment, and improve the tolerance of human body to chemotherapy. Therefore, a reasonable diet should be arranged during chemotherapy. About 70% of malignant tumor patients need radiotherapy, but while radiotherapy kills cancer cells, it also kills many normal cells indiscriminately. Therefore, patients may suffer from various discomforts during radiation therapy. Radiotherapy is regarded as a heat and poisonous evil in Chinese medicine, which is most likely to deplete fluids and cause symptoms of Qi and Yin deficiency: dry mouth and little energy, general weakness, red tongue without coating, and occasional nausea. Therefore, unlike chemotherapy, which causes mainly Yang deficiency, patients after radiotherapy tend to have Yin deficiency. The diet after radiotherapy should prohibit spicy and hot, fragrant and dry drugs and foods that hurt yin, but more yin nourishing and cool foods and tonic medicines can be eaten, such as bird’s nest, turtle, silver fungus, sea cucumber, lotus seeds, etc., and fruits such as apricot, peach, plum, raisin, red date, pineapple, prune, orange, tangerine, grapefruit, etc., but not too much, otherwise it will affect the patient’s gastrointestinal function. Fourth, good living habits Hao Xishan, chairman of the Chinese Anti-Cancer Association and academician of the Chinese Academy of Engineering, pointed out at the 21st World Cancer Congress that among the lifestyle factors that cause cancer, smoking is currently the largest preventable cancer-causing factor in the world. Smoking causes 80 to 90 percent of lung cancer deaths worldwide, and in developing countries this proportion reaches 30 percent. In terms of prevention, only 9 percent of countries currently require smoking bans in bars and restaurants, and 65 countries report not implementing any national smoke-free policies. David Hale, former president of the International Union Against Cancer, said, “I can’t say that I’ve ever seen that. Hale said, “I can’t tell you which foods consumed regularly may cause cancer, but one thing is certain, overeating leads to obesity, and obesity is one of the causes of cancer.” The leading American cancer research institute reports that bad habits account for 35 percent of cancer-causing factors. In view of this, paying attention to lifestyle prevention will keep many people away from cancer. V. Spiritual care and humanistic care Emotional and spiritual factors play an important role in the development of tumor. According to Chinese medicine, violent anger hurts the liver, excessive happiness hurts the heart, worrying hurts the spleen, excessive sadness hurts the lung, and fright hurts the kidney. The principle of regulating the spirit is to “keep the spirit inside, nourish the quiet and hide the spirit”, to be satisfied with what we have, to move our emotions, to be cautious of joy and anger, to think less and to worry less. In today’s society, work pressure, fast-paced life, many people often feel exhausted, very easy to produce anxiety, depression, in a state of subhealth. This is a danger signal, so you must learn to regulate the mood. In order to really adjust the emotions, we must do “calm and empty, the real gas from the”. Many people in the stock market have insomnia and elevated blood pressure, the reason for this is that it is difficult to maintain a stable state of mind is an important factor. People want to maintain a calm state of mind, should be “wise in the round and line in the square”, prior consideration as comprehensive as possible, deal with decisive and resolute. The plan is in the person, the success is in the sky, do not pay too much attention to the results, as long as the best effort can be.
