1.Psychological support Relatives should keep abreast of the patient’s ideological situation, in addition to physical care, should also pay attention to the spiritual support, timely elimination of the patient’s concerns and tensions so as to cooperate with the treatment. 2.Protect the irradiation field “mark” Before radiotherapy, the doctor will accurately determine the irradiation site and draw a red line as a radiotherapy mark. The radiotherapy mark is as important as the surgical site, and must be kept clear. When the color line becomes pale, the doctor should be asked to draw a clear line, and the “mark” must not be washed off; otherwise, the redrawing of the line may not be exactly the same as the original one, thus affecting the efficacy of the treatment. 3, dietary management patients often due to radiation damage, anorexia, nausea and vomiting and other adverse reactions, should be for the patient’s specific situation, strengthen nutrition. Such as encouraging more vitamin A-rich vegetables, more milk, cod liver oil, eggs and other high-protein easily digestible diet, in order to facilitate the body to repair damaged tissues. It is important not to let the patient have significant weight loss during radiotherapy, experience shows that: good appetite, eating more for tumor treatment and side effects are beneficial to overcome. During radiotherapy, some patients also have changes in sense of smell and taste, such as: bitter mouth, unsweetened sugar, unable to bear the smell of cooking, etc. Therefore, in food preparation, attention should be paid to color, aroma and taste, small amount of multiple meals, appropriate pain control before meals, and taking a walk before meals. At the same time should ban smoking and alcohol, avoid spicy fried and other stimulating food and hard food, encourage patients to drink more soup. Accelerate the excretion of toxins in the body. 4, irradiation field skin care Radiation irradiation will occur after the skin of different degrees of acute reaction, manifested as erythema, burning sensation, itching, breakage and flaking. Reduce the acute skin reaction caused by radiotherapy method is: keep irradiation field skin clean, dry, prevent infection, local skin to avoid stimulation, to do “five do not four forbidden a taboo a not”. Do not scratch with your hands, do not wear rigid high-necked clothes (neck irradiation), do not expose to strong sunlight, do not do infrared and other kinds of physical therapy; prohibit the sticking of adhesive tape or adhesive plaster, prohibit injections, prohibit hot compresses, prohibit self-medication; avoid soap or skin cream scrub; do not apply irritating or heavy metal-containing drugs, such as iodine, mercuric acid, flower oil. For the reaction area which needs to shave beard or hair, use electric scraper. 5, head and neck radiotherapy reaction care Head and face irradiation can often cause oral mucosal congestion and edema, ulceration, dry mouth, pain, difficult to eat, easy to complicate the infection, and in severe cases, affect swallowing. Prevention and treatment methods include: oral irradiation should be removed beforehand dentures, gold teeth, to reduce the oral mucosal reaction; oral mucosal irradiation, salivary secretion, as well as changes in the composition of the chemotherapy, resulting in an increase in the rate of dental caries, the patient should be asked to use fluoride toothpaste; to maintain oral hygiene, drink more tea; rinse the mouth with Duo Bei’s liquid four times a day, rinse the nasal cavity with saline, with compound peppermint oil nasal drops; oral ulcer cream, tin-like bulk, two-dose laryngopharyngeal wind The patient should be advised to quit smoking and drinking and avoiding alcohol and tobacco.

Radiotherapy is one of the three major treatments for malignant tumors, which is a treatment method of irradiating tumors with various kinds of rays of different energies to inhibit and kill cancer cells. Radiotherapy can be used alone or in conjunction with surgery and chemotherapy as part of comprehensive treatment to improve the cure rate of cancer. A period of radiotherapy to reduce the size of the tumor before surgery can give the inoperable patient a chance to have surgery. For advanced cancers, palliative radiotherapy can be used to relieve pressure and pain.
