The World Health Organization has provided the following definition of palliative care for patients with advanced cancer: active, comprehensive medical care for those whose disease has failed to respond to treatment. The aim is to achieve the best quality of life for the patient and family. Patients who cannot be cured should receive further palliative care and reasonable medical care, but due to the traditional prejudice against cancer and death, as well as the limitations of the existing medical system and conditions, patients with advanced cancer are basically in a state of helplessness, resulting in a large number of patients with advanced cancer not receiving reasonable treatment and proper placement, and suffering from the great physical and mental pain, economic loss, family unrest, and increased social and economic hardship caused by cancer. As a result, a large number of advanced cancer patients are denied reasonable treatment and proper placement, and suffer from great physical and mental pain, economic loss, family unrest, and increased burden on society and workplace. When anti-cancer treatment is terminated because it is no longer beneficial, the palliative care strategy, which aims to let patients with advanced cancer live better or even longer, becomes the leading strategy. Palliative care is also known as palliative care. The basic concept of palliative care is to provide active and comprehensive medical care to patients with life-threatening cancer; to recognize that life is a process and death is the end of life; and to advocate neither hastening nor delaying death. Cancer palliative care opposes abandonment of treatment; opposes overtreatment; opposes euthanasia; and opposes any disrespect for life. The purpose of cancer palliative care is to improve the quality of survival of cancer patients; to help cancer patients face difficulties with a calmer state of mind and stronger perseverance; to help cancer patients live actively until death; to help cancer patients’ families face reality and bear the blow. The main task of palliative care is to relieve the symptoms and complications caused by cancer itself and treatment, and to alleviate the physical pain and psychological burden of patients. In a simple word: to let patients live with quality and walk with dignity. Palliative care for advanced cancer patients is not limited to the general concept of “medical treatment”, but should also include solving a series of psychological, emotional, spiritual and social needs of patients and their families, so that they can receive adequate treatment, especially spiritual and psychological care and comfort. Palliative care for advanced cancer patients requires not only the direct participation of medical professionals, patients and their families, but also the joint efforts of psychological and social workers and a large group of volunteers. In conclusion, palliative care for patients with advanced cancer aims to improve their quality of life and enable them to walk through the last stage of their lives in as relaxed a state of mind as possible.
