The development of brain metastases means that the prognosis is poor, and without treatment, most patients tend to die within months or even weeks. The appropriate treatment measures for different patients can extend their survival time, relieve their suffering and improve their quality of life.
There are many factors that contribute to the prognosis of metastatic brain cancer, one being how well the primary cancer is controlled, two being how well the primary cancer responds to treatment, three being whether it is combined with metastases from other organs throughout the body, and four being the location and number of intracranial metastases.
