Treatment and care of cancer pain Pain is the most common symptom of cancer patients. According to the data, 50% of cancer patients have different degrees of pain, and 70% of advanced cancer patients have pain symptoms, 30% of which are unbearable and severe. Therefore, effective pain control is an important subject to improve patients’ survival quality. The treatment of pain should pay attention to the following points: Firstly, the patient’s pain level should be correctly assessed. Generally, the pain level is classified as mild pain, moderate pain and severe pain, and the corresponding treatment plan should be formulated according to the pain level. Thirdly, for those who have poor effect of single drug, the combination of drugs can enhance the analgesic effect and reduce the dosage of drugs. Second, the time of drug administration is also important. Many patients take drugs only when they are in pain, and the correct method is to give drugs on time according to the regularity of pain, which can reduce the dose of drugs. Fourthly, we should pay attention to patients’ psychological care. Many cancer patients will have different degrees of fear, anxiety and despair, and these bad emotions will lower the pain threshold and aggravate the pain, so family members should cooperate with medical and nursing staff to do a good job in patients’ ideological work, establish a new concept that cancer is treatable, listen carefully to patients’ complaints, help patients to kindle the dawn of hope from deep inside, increase some amateur activities to transform patients’ attention to the disease, and apply some antibiotics if necessary. If necessary, some antidepressants and anti-anxiety drugs can be applied to get better results. Fifth, active anti-cancer treatment, such as spinal metastatic cancer can cause severe pain due to nerve compression, and active radiation therapy can often treat the pain at the root.
