Is it okay to be in a coma with advanced brain cancer?

Late stage of brain tumor can lead to space-occupying effect, causing severe increase of intracranial pressure. In addition, if it causes compression of functional area, it can cause epileptic seizure, and severe cases can lead to coma and other symptoms. Active treatment to reduce intracranial pressure should be carried out, and radiotherapy and other methods should be used for treatment. If the opportunity for surgery has been lost, in this case, only oxygen can be inhaled, and symptomatic supportive nutrition treatment such as hanging nutrient solution can be used. Late stage of intracranial malignant tumor often causes severe symptoms of increased intracranial pressure.
