Nasopharyngeal cancer is a common tumor in otolaryngology and head and neck surgery. It is called “Guangdong cancer” in China because it has the highest incidence in China, and “China cancer” in the world because it has the highest incidence in the world. In recent years, the incidence of nasopharyngeal cancer has been increasing, and the first treatment option is radiotherapy. Radiotherapy is radiation therapy, which is very good and effective in treating many cancers, especially nasopharyngeal hypofractionated squamous cell carcinoma (NPC), but this treatment can have significant side effects. Therefore, radiotherapy needs to be carefully arranged in advance so that the site of radiotherapy is as small as possible and the treatment is very targeted. The following are the ways to deal with the side effects caused by radiotherapy for patients. 1, fatigue: during radiotherapy, the body uses a lot of energy, while the pressure brought by the disease, the daily radiation on normal cells can lead to fatigue. Most people will feel tired after 3-4 weeks of radiotherapy, and will feel more fatigued as the radiotherapy continues. It takes 3-6 months after the end of radiation therapy for the weakness and fatigue to subside. During radiotherapy, patients should do less. If you feel fatigued, then you should be less active and rest more during your free time. Go to bed early at night and possibly rest during the day as well. At this time, the company, help and understanding of family members are essential. 2. Skin: The skin in the treated area will be painful, look red and wrinkled. After a few weeks, the patient’s skin becomes dry due to radiation therapy. Most skin reactions will clear up a few weeks after radiation therapy ends. The skin treated with radiation therapy will be slightly darker than before. Patients should be careful with their skin. (1) Use cold water and mild soap; let the water run over the treated skin without rubbing. (2) Do not wear clothes that are too tight on the treated area. (3) Do not rub or scratch the sensitive area. (4) Do not put hot or cold things, such as hot towels or ice packs, on the skin undergoing radiation therapy, unless your doctor recommends it. (5) Do not rub powders, creams, perfumes, deodorants, ointments, lotions and household medications on the area being treated and for a few weeks after treatment, unless approved by your doctor. (Many skin products can leave a layer on the skin, which may hinder radiotherapy or recovery). (6) Do not expose the area that received radiation therapy to sunlight during and for one year after radiation therapy is completed. If you want to stay in the sun for a few more minutes, wear protective clothing (such as a wide-brimmed hat and a long-sleeved shirt) as well as using sunscreen. 3. Difficulty eating and drinking: Side effects also include problems with eating and digestion. During the treatment, the patient may have no appetite at all, plus the irritation of radiotherapy can lead to dryness in the mouth and throat and painful swallowing. However, it is very important to consume as much protein and calories as possible, even if you are not hungry. Patients who insist on eating well can better cope with the cancer and its side effects. Suggested measures: (1) If you feel pain when chewing or swallowing food, you are advised to eat liquid or semi-liquid food. Patient preparation by family members is needed to coax the patient to eat. (2) Eat when you are hungry and eat small meals. (3) Since eating very small amounts of food, you can increase the energy intake by: adding cream to food; drinking milk instead of water; family members making more vegetable or fruit juices for the patient to drink as a beverage or water. Emotion: Most patients feel depressed, scared, angry, defeated, lonely or helpless because of the word “cancer”. Poor emotion, coupled with the side effects of radiotherapy, will make the patient depressed or even broken, so the company, encouragement, understanding and smiles of family members are the greatest help. Do not let the patient see the family’s frustration. If necessary, psychologists can be asked to ease the situation. It is hoped that patients and family members should have sufficient psychological preparation during the treatment of nasopharyngeal carcinoma. The treatment of malignant tumor requires patience and a strong heart that is very capable of enduring pain and suffering. No matter how painful it is, don’t give up and insist on it. Radiotherapy for nasopharyngeal cancer is very effective, according to statistics, the average survival rate of nasopharyngeal cancer after radiotherapy is more than 75% in 5 years.
