1, to maintain emotional stability: clinical practice shows that patients who are doubtful and frightened during chemotherapy often have heavier adverse reactions in chemotherapy; while patients who are open-minded and generous have lighter reactions. Therefore, all tumor patients who need chemotherapy should have the confidence to win and receive chemotherapy in a happy mood in order to reduce adverse reactions and obtain the best curative effect. 2. To arrange diet reasonably: patients will have gastrointestinal reactions such as mouth ulcers, loss of appetite, nausea and vomiting or diarrhea during chemotherapy. In the diet should eat more light, nutritious and easy to digest food. You can often eat lean meat, fish, dates, peanuts and other foods. This is very useful to prevent or reduce the decline in blood cell count due to bone marrow suppression. If the patient has symptoms of anemia, eat more animal liver or heart, egg yolk, lean meat, and spinach, prunes, oranges, grapefruit and figs. It is important to eat more edible mushrooms rich in polysaccharides such as shiitake mushrooms, mushrooms, monkey head mushrooms and fungus to improve the immune function of the body and inhibit the growth and reproduction of cancer cells. When patients use chemotherapy drugs such as cyclophosphamide which are mainly excreted by kidney, they should drink more water to reduce the damage of drugs to kidney. 3. Pay attention to protect the skin: Patients should strengthen the maintenance of the skin if skin damage occurs during chemotherapy, and prohibit irritating detergents. If dermatitis or hyperpigmentation occurs, do not scratch or apply ointment indiscriminately. If hair loss occurs, the protection of the scalp should be strengthened to prevent exposure to the sun. 4.To avoid pregnancy: Female tumor patients should avoid pregnancy during chemotherapy because a considerable part of chemotherapy drugs have mutagenic and teratogenic effects. 5. To pay attention to the prevention of infection: Because chemotherapy drugs can inhibit the bone marrow and immune function of human body to different degrees, the anti-disease ability of the organism is reduced, thus it is easy for patients to have many kinds of infectious diseases. Therefore, patients should live a regular life during chemotherapy, combine work and rest, and ensure sufficient sleep. In addition to being bedridden, patients should perform appropriate exercise to enhance the body’s resistance to disease and avoid infectious diseases as much as possible.
