The last symptoms before death from advanced brain cancer?

What are the last symptoms before death from advanced brain cancer?

1. Regardless of whether it is brain hernia caused by increased intracranial pressure or direct compression of brain tissue by a tumor, the end result is that the patient's important brain life centers are damaged and consciousness is disturbed, mostly manifested as coma, relaxation of muscles throughout the body, unequal pupil diameters on both sides, weakened or absent light reflex, and no obvious response to external mechanical, sound, light, pain and other stimuli. Patients may have intermittent or continuous convulsions, and ultimately die due to dysfunction of the respiratory and cardiac centers, resulting in a drop in blood pressure, a slow heart rate, a decrease in blood oxygen saturation, and sudden or rapid cessation of breathing and heartbeat.

2. Most of the malignant tumors in the brain are gliomas. In the late stage of the tumor, as the tumor gradually grows, it can cause symptoms of increased intracranial pressure, which can cause headaches, dizziness, nausea, vomiting, impaired consciousness and even coma, so most of them have a poor prognosis. Late symptoms of brain cancer include severe headaches, projectile vomiting, sudden vertigo or epilepsy, visual impairment or diplopia, and even complete blindness.
