What are different types of brain tumors?
There are more than 100 types of brain tumors. The main categories are gliomas, metastatic tumors, pituitary tumors, primitive neuroectodermal tumors and benign tumors such as meningiomas. These types of brain tumors are usually classified according to the types of cells in which they were created and the severity of the tumor.
Gliomas are the largest of the different types of brain tumors. Gliomas come from the supporting tissue of the brain, which consists of glial cells. The most common type of glioma is astrocytoma, which is very malignant and can affect children and adults. Astrocytomas exert a cranial pressure that can lead to headaches, problems with balance, nausea and double vision. Such tumors are most common in children, can affect movement on one or both sides of the body and can cause problems with double vision and coordination. Their position means most of the brain glioma is not treated with surgery. These types of brain tumors are very malignant and are usually aggressive to treat chemotherapy, radiation,surgery or combination of two or more of three. They often return to remission and usually come like tumors of skin, lungs or breast.
pituitary tumors occur on or near the pituitary at the skull base. These types of tumors may have an adverse effect on the pituitary function - to a large extent responsible for checking the glandular body system that produces and regulates vital hormones. The pituitary tumors are more likely to be benign than many other species of brain tumors, but their proximity to the pituitary and brain is still doing very dangerous. Normally they are surgically removed and repetition is not as predominant as in malignant tumors.
Other malignant brain tumors include PET tumors that are very invasive and can occur anywhere in the brain. They are associated with severe headaches caused by increased skull pressure. Often occur near the brain, kdsE are referred to as medulloblastomas. Aggressive treatment is invited to stop PET tumors from metastasis and movement around the central nervous system.
The most common benign types of brain tumors are meningiomas. Meningiomas occur in a tissue that protects the brain and is located next to the skull. Meningiomas are slowly growing and patients often do not realize about them for many years before they are detected. In general, surgery is treated with good success, although they sometimes repeat or become malignant.
