Cancer is recognized worldwide as a health killer, but what scares many patients with advanced cancer is not how close they are to death, but cancer pain. Pain is one of the most dreaded symptoms for oncology patients and is often more daunting than death caused by cancer. So what exactly does cancer pain do to a patient? Pain is one of the most dreaded symptoms for tumor patients, often more dreaded than death caused by cancer. The incidence of cancer pain (cancer pain for short) is relatively high, with 30-40% of patients having moderate to severe pain at the time of cancer diagnosis and in the middle stages of cancer, 50% of adult and pediatric patients receiving anti-cancer treatment having varying degrees of pain, and 60%-90% of advanced cancer having pain. Cancer pain is not only a medical problem, it is also a social problem, and the specific goal of “achieving a world free of cancer pain by the year 2000” was proposed in 1982, but unfortunately this goal has not yet been achieved. After reading the above introduction, you should have some understanding of what effects cancer pain can have on patients. For patients with advanced cancer, controlling cancer pain can improve their quality of life in their limited life. Because of the inpatient environment of tumor ward, it is easy for patients to produce extreme tension and anxiety, at this time, somatic pain adds to their pain and misery. The harm of cancer pain Patients with cancer in all clinical stages may experience pain, and the harm caused by pain to them is similar. Cancer pain is not only unbearable for patients, but also brings a series of serious effects. For example, nausea and vomiting, loss of appetite, anxiety, fear, depression, reluctance to interact with others; loss of various body functions and reduced mobility; loss of confidence in life and treatment, etc. The physical, physiological and psychological damage caused by pain not only significantly affects the quality of life of patients, but also affects the implementation and effectiveness of treatment. Some patients lose their patience because their pain is not satisfactorily controlled, and they may even give up the chance to cure cancer radically. Therefore, cancer pain can cause serious harm and patients with all stages of cancer should actively receive pain relief treatment. Pain should be treated for all stages of cancer patients. In addition to reducing patients’ pain, pain relief treatment also helps improve the quality of life and contributes to the successful completion of anti-cancer treatment. Anti-cancer treatment itself can control pain, but it takes some time for pain relief to take effect. Therefore, before the radical anti-cancer treatment becomes effective, it is also necessary to actively carry out pain relief treatment so that the anti-cancer treatment can be successfully completed. In addition, for patients who have lost the chance of radical anti-cancer treatment, pain relief may be the only acceptable treatment for some patients, because pain relief treatment may enable tumor patients to survive with cancer for a long time in a pain-free state, so as to fight for treatment time and opportunity. After reading the above introduction, you have some understanding of what effects cancer pain will have on patients. Therefore, when a patient has cancer pain symptoms, as friends and relatives, we should try to accompany him, comfort him, encourage him and stimulate his fighting spirit to fight with cancer.
