It is necessary to treat old metastatic tumors. This is because although brain metastases are in the late stage of cancer, after effective treatment measures are implemented, the clinical symptoms of patients can be obviously alleviated, the quality of life can be improved and the survival time can be prolonged. Some patients with single brain metastases can survive for many years after surgical resection and postoperative radiotherapy. Therefore, it is still positive but meaningless for brain metastases. Brain metastasis occurs in the late stage of cancer. Generally speaking, it's not good, the squatting time is short, and it depends on what kind of cancer it is, as well as the old metastasis, whether it is single or multiple, and how some malignant tumors are. Melanoma is highly malignant, with brain metastases, and most of them can live for six months to one year. If it is pancreatic meningococcal metastasis, the survival time may be less than half a year, and some of them always turn to Liu Ru. Lung adenocarcinoma can also be used. After drug treatment, the survival time of target image is relatively long, reaching more than five years. In recent years, traditional Chinese medicine with the main functions of clearing away heat and toxic materials, softening and dispersing stones also has the function of inhibiting and killing tumor cells, which directly kills cancer cells in the process of circulation and operation. Commonly used drugs are rhubarb. Aloe Sophora tonkinensis in cowshed in Qing Dynasty. Radix Isatidis, Folium Isatidis, Flos Lonicerae and Radix Sophorae Flavescentis.
