Causes of death from grade 3 brain cancer

What causes sudden death from brain cancer? If brain cancer is not treated in time or is discovered late, the tumor will continue to grow, which will have serious consequences. Brain cancer cells can compress normal brain tissue, which affects the functions of the brain tissue, and some complications of brain cancer are also caused. In addition, brain cancer has a more serious consequence, that is, brain herniation, which can cause sudden death.

Brain herniation is an important factor causing sudden death from brain cancer. Brain herniation caused by brain cancer is due to the space-occupying effect of the tumor or brain edema and obstruction of cerebrospinal fluid circulation, which increases the brain volume and intracranial pressure, causing part of the brain tissue to shift and be squeezed into a lower pressure area through some anatomical fissures to form brain herniation. The herniated brain tissue compresses important structures or life centers, leading to serious consequences such as brain herniation, compression of respiratory and circulatory centers, and respiratory and cardiac arrest.
Generally speaking, when the tumor continues to develop and approaches the late stage, it is easy to occur if it fails to receive timely and effective treatment. However, some tumors are not large, but they are located in the midline and affect the cerebrospinal fluid ring in the early stage. If the cause is not eliminated, it will also cause brain herniation and sudden death, which is more common in gliomas and brain metastases.
At present, brain cancer is mainly treated with increased intracranial pressure, such as the use of dehydration drugs to reduce intracranial pressure. For cases where drug treatment is ineffective, palliative surgeries such as cerebrospinal fluid shunt, subtemporalis decompression, suboccipitalis decompression or craniectomy can be performed. It is important to detect it early and treat it as soon as possible to avoid the serious consequences of brain herniation.
