Brain metastasis prognosis is good?

Brain metastasis generally refers to brain metastasis of tumor. Tumors that can metastasize are malignant tumors. metastasis occurs at the advanced stage of tumor, so the prognosis is extremely poor. Patients die within 4 months from the discovery of brain metastasis. If active treatment is extended to 6 months at most, the cause of death of patients is mostly severe central injury. Brain metastases are often multiple lesions, which can cause neurological deficit signs in the early stage, such as hemiplegia, hemiparesthesia, speech dysfunction, visual impairment, mental abnormality or epilepsy. Later metastasis gradually increased, peripheral edema will obviously produce obvious symptoms of high intracranial pressure, may induce cerebral hernia, and cerebral hernia will affect the patient's respiratory circulation, resulting in central respiratory and circulatory failure, given dehydration to reduce intracranial pressure treatment, can alleviate the formation of cerebral hernia, but can only slow down its pace, and ultimately can not stop. Dehydration drugs ineffective, patients mostly died of central respiratory and circulatory failure.
