Brain cancer is a cancer that is present in human brain tissue, which is a set mass of brain cells grow abnormally and out of control. Most brain cancers can spread through brain tissue, but rarely spreads to other parts of our body.
Brain cancer is different from other cancers. Cancer of the brain or spinal cord known to rarely spread to other organs. Brain cancer cause local damage to normal brain tissue damage only in places where they appear. Brain cancer is a malignant cancer that can continue to grow and can lead to death.

Here are 4 Piece Brain Cancer Cause of Death:
1. Glioma
Gliomas are tumors that start from a group of glial cells. Tumors including gliomas, among others:
a. glioblastoma
b. astrocytomas
c. oligodendrogliomas
d. ependymomas
Astrocytomas
Most tumors that arise in the brain itself begins in glial cells called astrocytes. These tumors are called astrocytomas. Most astrocytomas can spread widely throughout the brain and fused with normal brain tissue, making it very difficult for surgery. These tumors can also spread along the main nerve system.
Astrocytomas divided into three groups, namely:a. Low-grade astrocytomas: type the slowest growing
b. Anaplastic astrocytomas: growing at a moderate rate
c. The highest grade astrocytoma (or glioblastoma): Type the 3rd is the fastest growing. These tumors make up about 2/3 of astrocytomas and is the most common type of brain cancer (malignant) that affect adults.
Oligodendrogliomas
Oligodendrogliomas are tumors that begin to grow in the brain cells called oligodendrocytes. Such as astrocytomas, most can infiltrate into nearby brain tissue and can not be completely removed by surgery. Oligodendrogliomas sometimes scattered throughout the central nervous system pathways but rarely spread outside the brain or spinal cord. Very aggressive type of tumor is known as anaplastic oligodendrogliomas. Only about 3% of brain tumors manifold oligodendrogliomas.
EpendymomasEpendymomas is a type of tumor that is derived from the ependymal cells that line the ventricles. Ependymomas can obstruct the outflow of the central nervous system of the ventricles, causing a condition called hydrocephalus.
Astrocytomas and oligodendrogliomas Unlike, ependymomas usually do not grow infiltrate normal brain tissue. As a result, some (but not all) ependymomas can be completely removed and cured by surgery. Spinal ependymomas have the greatest chance to be cured through surgery. Ependymomas can spread along the CSF pathways but do not spread outside the brain or spinal cord. Its most aggressive form known as anaplastic ependymomas and usually can not be cured by surgery. Only about 2% of brain tumors manifold ependymomas
2. MeningiomaMeningiomas arise from the meninges, the layer of tissue that surrounds the outside of the brain and spinal cord. Meningioma contribute to about 1 in 3 primary brain cancer and cancer of the spinal cord. They are the most common brain tumor in adults.
The risk of these tumors increases with age. They were about two times more common in women. In some cases these tumors are genetic (inherited), particularly in those with neurofibromatosis (benign tumor syndrome in nerve tissue).
Meningiomas cause symptoms by pressing the brain or spinal cord. About 4 out of 5 meningiomas are benign, and most can be cured with surgery. But some meningiomas grow very close to vital structures in the brain and can not be cured with surgery alone. A small number of meningiomas are malignant and may come back many times after surgery or even spread to other parts of the body.
3. MedulloblastomasMedulloblastomas is growing tumors of neuroectodermal cells (primitive nerve cells) in the cerebellum. They are a fast-growing cancer and often spread throughout the cerebrospinal fluid pathways, but they can be treated with radiation therapy and chemotherapy. Medulloblastomas occur more frequently in children than in adults. They are part of a class of tumor called primitive neuroectodermal tumors (PNETs) that can occur in a large brain and elsewhere in the central nervous system.
4. GangliogliomasTumor-containing neurons and glial cells called ganglioglioma. It is very rare in adults and has a high prospect of cure with surgery alone or surgery combined with radiotherapy.
