One of the most disturbing symptoms accompanying cancer is pain, which not only causes unbearable and great suffering to the patients themselves, but also brings many burdens to their families and society. According to some data, about millions of cancer patients suffer from cancer pain every day in China, and 30% to 45% of them suffer from severe pain. Cancer pain seriously affects the quality of life and survival, and pain removal treatment is as important as tumor treatment; about 80% of cancer pain can be significantly relieved by regular treatment, and patients can live “pain-free” with dignity. Cancer pain is usually divided into soft tissue cancer pain, cancer bone pain and cancer neuralgia according to the different tissues invaded by tumors, among which cancer neuralgia is the most difficult to treat. Because cancer pain invades nerve tissues, it makes treatment very difficult. With the new method-Interventional Pain Relief Technology, which is produced by high technology, it brings hope to cancer pain patients, and more and more advanced cancer pain patients are able to relieve cancer pain and get good quality of life, which can also significantly improve the physical and mental health of patients. Therefore, when a tumor patient has pain, please do not hold it back, but go to receive treatment as soon as possible. Minimally invasive interventional technology for cancer pain treatment is an effective nerve destruction treatment for intractable cancer pain by using targeted puncture technique under the guidance of imaging equipment, placing the puncture needle into the treatment area in the body and applying various nerve-destroying drugs to block the nerve conduction related to pain for a long time. It is mainly used for the treatment of intractable cancer pain. Compared with surgery, it is relatively simple to operate, does not require special instruments and equipment, can be repeated, has few complications, and is suitable for elderly and frail tumor patients.
