What are gliomas brain tumor and its causes

 

 

What are gliomas brain tumor and its causes Gliomas are the general name of the brain tumor disease used to describe the tumor formed in the glial cells, which are the supporting tissue of the brain There are different degrees of gliomas that show their growth potential and aggression. This group of tumors includes glioblastomas. Glioblastoma symptoms may be similar to those of other gliomas There are many types of gliomas, including astrocytomas, oligodendrogliomas, and ependymomas. The most common type of glioma is astrocytoma. Gliomas constitute approximately 30% of all brain tumors, they are generally observed as malignant, there are also benign brain tumor types.

 

Brain tumor symptoms

 

Brain tumor symptoms General symptoms of brain tumors can include headache, seizures, nausea and vomiting. They also give symptoms depending on the regions they settle in. Epilepsy (episode seizure) may occur as the first symptom in some patients and may cause personality changes For this reason, in malignant gliomas, the tumor should be destroyed by various treatment methods such as brain surgery, gamma Knife radio surgery, chemotherapy, and radiotherapy Epileptic attacks Nausea and vomiting are observed Occasionally, double vision or visual system disorders are observed, deterioration in physical walking, speech disorder, memory loss in the brain memory system, emotional disorders, unusual behavioral disorders in behavior

What are the causes of brain tumor and treatment methods

 

Brain tumor has not been scientifically determined to be connected to a definite cause, it can occur for many reasons. Brain tumor is a type of brain disease that can develop at any age. Factors that can cause brain tumor disease, being in areas with radiation for a long time, virus infections, electromagnetic, etc. can be Astrocytomas are glial cell tumors that develop from connective tissue cells called astrocytes and are the most common primary intraaxial brain tumor, accounting for nearly half of all primary brain tumors. They are most commonly found in the cerebrum (the large, outer part of the brain) as well as in the cerebellum (located at the base of the brain) strocytomas can develop in adults or children. High-grade astrocytomas, called glioblastoma multiforme, are the most malignant of all brain tumors. Glioblastoma symptoms are generally the same as those of other gliomas. Pilocytic astrocytomas are low-grade cerebellum gliomas commonly found in children. In adults, astrocytomas are more common in the brain.

 

 

Brainstem gliomas, also commonly called brainstem tumors or infiltrating DIPGs, are rare tumors found in the brainstem. Because of their remote location, they are intertwined with normal brain tissue and affect the delicate and complex functions that this area controls, they usually cannot be surgically removed. These tumors occur most frequently in school-aged children, where they are responsible for most childhood deaths from primary brain tumors Ependymomas develop from ependymal cells lining the ventricles or in the spinal cord. Ependymomas are rare and make up only 2 percent to 3 percent of primary brain tumors. However, they make up about 8 percent to 10 percent of brain tumors in children and are more likely to affect those younger than 10 years old. The most common location for ependymomas in children is near the cerebellum, where the tumor can block the flow of cerebrospinal fluid and cause increased pressure inside the skull (obstructive hydrocephalus). These tumors can spread to other parts of the brain or spinal cord (drop metastases due to the flow of spinal fluid) Mixed gliomas (also called oligo-astrocytomas) are made up of more than one glial cell type. Their diagnosis as a distinct tumor type is controversial and can be resolved by genetically screening the tumor tissue. These tumors are usually found in the brain and are most common in adult males Oligodendrogliomas form from oliogodendrocytes, brain supporting tissue cells, and are usually found in the brain. About 2 percent to 4 percent of primary brain tumors are oliogodendrogliomas. They are most common in young and middle-aged adults and are more likely to occur in men. Seizures are a very common symptom of these gliomas (affecting 50 percent to 80 percent of patients), as well as headache, weakness, or speech problems. Oligodendrogliomas typically have a better prognosis than most other gliomas Optic tract gliomas are a type of low-grade tumor located in the optic nerve, or chiasma, where they infiltrate the optic nerves, which usually send messages from the eyes to the brain. People with neurofibromatosis are more likely to develop them. Optic nerve gliomas can cause vision loss and hormone problems as these tumors are usually located at the base of the brain where hormonal control is located. Gliomas that affect hormone function may be known as hypothalamic gliomas.
