Brain tumor types according to WHO

Today, there are over 120 brain tumor types. This is inevitably based upon the classification system of World Health Organization to identify variable brain tumor types. The WHO has classified brain tumor by the origin of cell and the behavior of cells. The kind of brain tumor could vary from least aggressive which are known as benign to aggressive kinds that are also popularly called malignant. Some types of tumor are offered a grade that ranges from Grade I that are least malignant to Grade IV which care regarded as most malignant which in turn signifies growth rate. There are many variations in system of grading purely dependent upon the type of tumor. The grade as well as classification of a human tumor efficiently helps the prediction of its behavior.


Exploring variable brain tumor types

The different brain tumor types can be classified as acoustic neuroma, astrocytoma which is further divided into grade I -pilocytic astrocytoma, grade II – low grade astrocytoma, grade III – anaplastic astrocytoma and grade IV – glioblastoma or GBM. The other types include chordoma, CNS lymphoma and craniopharyngioma. There are other gliomas like brain stem glioma, ependymoma, mixed glioma, optic nerve glioma and subependymoma. The other common brain tumor types are medulloblastoma, meningioma, metastatic brain tumors, oligodendroglioma, pituitary tumors, primitive neuroectodermal or PNET, schwannoma and other brain related conditions. The brain tumor types commonly found in children as compared to adults are brain stem glioma, craniopharyngioma, ependymoma, juvenile pilocytic astrocytoma or JPA, medulloblastoma, optic nerve glioma, pineal tumor, primitive neuroectodermal tumors or PNET and rhabdoid tumor.

All about brain tumor types

It is important to be noted that tumors are of different subtypes. In addition, few of the brain tumor types are integrated with different names. Eventually, it is quite significant to see that a benign or nonmalignant tumor is as difficult as a malignant brain tumor to be treated. Immaterial of its type a brain tumor is a tumor that is found inside central spinal canal or the cranium. It is generally caused via uncontrolled and abnormal cell division. This extra cell growth called as brain tumor obstructs normal activities. However, a tumor can damage the healthy tissue of brain by accelerating the pressure and pushing or in turn invading patient’s brain. Depending upon location of tumor in brain a person could display the following symptoms; sever headaches in morning, nausea, seizure, fits or convulsions, weakness in one side of body, difficulty in thinking, speech, hearing or vision, disorientation and confusion, body balance and memory loss. In general, there are two types of brain tumor benign which are non cancerous and malignant tumors that are cancerous. Benign tumors grow slowly and can be viably removed if accessible. In inaccessible cases the tumor proves to be dangerous. A malignant tumor on the contrary grows rapidly and invades tissue of brain and need immediate medical help. Brain tumor can be effectively diagnosed via CT and MRI scans and confirmed via biopsy procedure.  Depending upon the magnitude of issue caused by brain tumor types a doctor could suggest an ideal treatment.


What are the different brain tumor types?

You may have heard of brain tumors but have no idea as to what are the different brain tumor types. A brain tumor is very serious and dangerous to life. A brain tumor is essentially intracranial or inside the cranium of the brain. It is a solid neoplasm which is an abnormal growth of cells that is within the central spinal cord or within the brain.

Brain tumors types are abnormal and sporadic cell division within the brain itself. They also affect the pituitary gland, the skull, the lymphatic tissue, the cranial nerves or the pineal gland. Brain tumors are commonly spread from cancerous cells in the body of a person suffering from cancer which are called as metastatic tumors.


Different brain tumor types

There are two essential brain tumor types that can be treated; these are benign and malignant types. Some tumors begin in the brain and are called as primary tumors and those that are metastatic tumors are a result of some cancerous or disease causing cells spread from other parts of the body to the brain. Brain tumors types vary even in the symptoms, some brain tumors are detected with visible symptoms while other show up only in an imaging scan or an autopsy.

  • Glioma brain tumor:  The glial cells are the place from where this tumor originates in the brain or spine.
  • Meningioma brain tumor: Arising from meninges or the membranes encompassing the central nervous system, this brain tumor comes out in diverse forms. It is one of the most common primary brain tumors affecting individuals.
  • Pituitary adenoma brain tumor: Arising from the pituitary gland which is one of the significant parts of the cranium of the brain, this brain tumor can range from the smallest to as large at 10 mm in size. They are often detected only through brain scans or autopsies.
  • Nerve sheath brain tumor: Originating in the nervous system, this tumor is one of those brain tumor types that are primarily made up of myelin around the nerves of the nervous system.

How can one treat brain tumor?

A neurosurgeon is often a person who can treat all brain tumor types. The most common treatment for brain tumors is to completely remove it in case it does not affect any immediate or serious part of the brain through surgery. Other treatments include radiation therapy where the brain tumor is treated with radiation waves. This will ensure that the brain tumor reduces in size or the cells within the tumor die in order to prevent the spread of the tumor. Gamma knife treatment is also a very effective way of treating all brain tumor types as the gamma knife machine cuts the brain tumor cells by isolating gamma waves on the brain tumor.

Chemotherapy is also a commonly used treatment for treating all brain tumor types.

Successfully recoveries from all brain tumor types are present all over the world, as neurosurgeons have managed to treat them in order to give people a second life with the most advanced technologies at hand.
