Cancer pain is one of the common symptoms of tumor patients, which often causes fear and anxiety. Many patients or doctors mistakenly think that cancer pain is something patients must bear, and it will naturally stop after the tumor is cured; or they think that cancer pain treatment is only symptomatic treatment, which can only improve the symptoms and has little significance, while anti-tumor treatment is the cure; some other patients are afraid of becoming addicted to painkillers, forcing themselves to endure severe pain and struggle tenaciously with cancer pain. Whenever I see these patients in the ward, as an oncologist, I feel compassionate and painful. Today I would like to talk to you about the standardized treatment of cancer pain today. The World Health Organization (WHO) has made “pain-free” a basic human right of cancer patients. For pain patients, our doctors should first identify the cause of pain and evaluate it, and then follow the WHO’s three-step pain relief principle to administer effective drugs in a timely, timely, safe and individualized manner. The use of adjunctive medications in combination with pain relief, such as antidepressants, convulsants, hypnotics and sedatives, can be chosen at any stage of pain management depending on the condition. Effective pain control requires a combination of treatments, including other symptom assessment, pharmacological and non-pharmacological treatments, and education of patients and their families on how to obtain reasonable analgesia. As we all know, if cancer pain is not relieved, patients will feel extreme discomfort, which may cause or aggravate patients’ anxiety, depression, fatigue, insomnia, loss of appetite and other symptoms, and seriously affect patients’ daily activities, self-care ability and overall quality of life. Therefore, cancer pain cannot be endured by yourself and must be treated formally so as to reduce pain or even reach pain-free. Therefore, when you feel pain, you should tell your family, friends and our medical staff in time to get everyone’s support and help to eliminate the disease pain through our treatment. This is also an important part of palliative care for tumor patients. When it comes to palliative care, people will first think that palliative care is equivalent to “I can’t be cured, so I must go to hospice” or similar. But this is not the case. Let’s try to give it a new definition. Palliative care is a comprehensive approach to treating serious diseases (such as cancer), providing multiple layers of support for patients, families and doctors. Palliative care, especially for cancer pain, should not be used at the last stage of life, but should be carried out early so as to help patients better cooperate with anti-cancer treatment, improve their quality of life, prolong their survival, relieve the psychological pressure of patients and their families, and hope that every patient with advanced cancer – “live like the splendor of summer flowers, die like the quiet beauty of autumn leaves “.
