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.
