What is a malignant brain tumor? The brain is made up of different cells: - Neurons (neurons that are responsible for transmitting nerve messages... these cells are unable to multiply and become cancerous... - Neuroglia that are responsible for supporting and feeding neurons.... The tumor originating from these cells is called a glioma brain tumor.... - Meningocytes, which are the cells that make up the meninges, are the membranes that cover the origin of brain cells... itself Neuroglia are divided into 3 general types: - Astrocyte Oligodendrocyte Appendium If any of the aforementioned cells (except neurons) undergo unbridled successive divisions, a tumor is formed, and if it invades the surrounding tissues, it is known as a malignant brain tumor... What is the prevalence of brain tumors? Approximately 10 to 17 people out of every hundred thousand people have a brain tumor.. About 50 to 75% of brain tumors are primary tumors.. That is, they arise from the cancerous cells mentioned above, and the rest are absorbed by metastatic tumors. They include lung, breast and skin melanoma. The relative prevalence of brain tumors in children is higher than in adults and they make up about 20% of brain tumors. It does not invade surrounding tissues, but due to the limited space inside the skull, these benign tumors can cause very severe symptoms. Malignant brain tumors rarely metastasize outside the brain, and most of these tumors metastasize to other areas of the brain itself. give... types of malignant brain tumors Malignant brain tumors are rapidly growing and aggressive and can involve healthy brain tissues... Treatment often includes chemotherapy, radiation therapy, and surgery, which is performed with the help of a brain tumor surgeon. Next, we will learn about the types of malignant brain tumors: ### Astrocytoma This type of tumor is one of the most common brain tumors and accounts for nearly 80% of glial brain tumors.. This tumor is mostly seen in the fourth to sixth decade of life and mostly originates from the cerebral hemispheres.. Severe cases, they usually do not live more than 15 months.... ### Oligodendroma This class of tumors constitutes 5 to 15% of glial brain tumors and often occurs in the fourth and fifth decades of life.. These tumors often originate from the cerebral hemispheres.. These patients usually have a series of neurological symptoms (in most cases, seizures) for several years before diagnosis.. And if the tumor is undifferentiated (grade 3), the survival of the patient is between 5 and 10 years.... ### Ependymoma These tumors make up about 5 to 10% of glial brain tumors and are mostly seen in the first two decades of life.. This means that we will see these tumors more often in children.... This tumor is usually seen in connection with neurofibromatosis type 2 (NF2) disease, which is a genetic and congenital disease.... One of the common manifestations of neurofibromatosis type 2 is the creation of multiple tumor-like lesions throughout the body. is (similar to a wart).... These people are usually at risk for brain tumors and are usually at risk for brain tumors.... ### Medulloblastoma This tumor is seen in most cases in children and originates only from the cerebellum... This tumor is very malignant and has a very bad prognosis if not properly treated... One of the unique features of the tumor is its sensitivity to radiation therapy (Radiosensitive). When the lymph nodes of the brain undergo cancerous changes, primary brain lymphoma develops. However, due to the role of immunodeficiency in the development of this type of cancer, the most common type of brain cancer is in people with a weak immune system (such as people with HIV). This type of cancer can occur at any age, but its prevalence increases significantly after the age of 60. They have a very strong relationship.. This infection has a relatively high prevalence in immunocompromised people, and its symptoms include purulent sore throat, enlarged cervical lymph nodes, painful swallowing, and fever. ### Meningioma Meningiomas are often benign tumors that originate in the meninges or the lining of the brain. These tumors usually cause symptoms that lead to the diagnosis of these tumors due to the pressure they put on the underlying brain tissue. These symptoms usually include headaches or seizures. The tumor is related to neurofibromatosis 2... ### Metastatic tumors Malignant tumors that are located in different parts of the body can spread through the blood or the lymphatic system of the body and involve different parts of the body. As mentioned, this process of spreading malignant cells in the body is called metastasis. About a quarter of brain tumors are metastases. The most common places of these metastases are: - Lung - chest - Skin (especially melanoma) - kidney - Digestive system - Pituitary tumors Pituitary tumors are common brain tumors and are benign in almost all cases... Due to the problem that the pituitary gland has in regulating the secretion of body hormones, these tumors can cause different hormonal symptoms in the body, which will be explained about these symptoms... What are the symptoms of a malignant brain tumor?... Depending on the size, location and type of tumor, we will see different symptoms: - Headache: Headache is one of the most common symptoms of brain tumors.... Due to the compressive effect of the tumor on the adjacent tissues, the headache of these people is localized. Due to the compressive effect of the tumor on the adjacent tissues, the patient experiences convulsions... The convulsions of these patients may be diffuse or involve only one side of the body... Some areas of the body may experience numbness or muscle weakness... Vision (one-way or two-way) as well as double vision... In people with a pituitary tumor, the person's field of vision is limited from the sides.... - Endocrine disorders: as explained, pituitary tumors lead to hormonal disorders in a person... Some of these symptoms are: - milk leakage from the breast (galactorrhea) - Disturbance in menstrual cycles, which is usually in the form of amenorrhea... - Infertility: These people may suffer from ovulation disorders and infertility... sometimes these symptoms are considered as hidden symptoms of a brain tumor... How is a brain tumor diagnosed?... If there is any doubt about the existence of brain tumors, these tumors can be diagnosed with the help of MRI or CT scan... The preferred and accurate method Another is the use of MRI of the brain, and with its help, tumors can be easily distinguished from similar lesions such as brain abscess or cyst. But a definitive diagnosis is made with the help of a malignant brain tumor biopsy. Around the brain, there are layers of meninges that form a structure called the blood-brain barrier. These structures prevent many things and drugs from entering the brain. are injected intravenously) can be difficult and challenging.. Sometimes, to solve this problem, they use the method of direct injection of drugs into the central nervous system, which is called IT or IntraTechal injection. - Temozolomide - Procarbazine - Lomustine - Vincristine Usually, procarbazine, lomustine and vincristine are used as a three-drug regimen, and it is called the PCV regimen... Malignant brain tumor surgery With the help of a brain tumor surgeon, the tumor can be removed from the patient's body... Benign tumors, especially meningioma, which are separate from the brain tissue, are easier to remove and have fewer complications.. For detailed information on the **brain tumor surgery cost** and treatment planning, consultation with a specialist doctor is necessary... Postoperative complications of malignant brain tumor After the surgery, parts of the healthy brain tissue are removed and scars are created in these areas... For this reason, the person may experience complications such as numbness, weakness, or seizures... Depending on which part of the surgery was performed, these complications will be different.. Also, if the surgery is not performed in a sterile manner, there is a possibility of infection (meningitis and encephalitis). Brain tumor surgery is a heavy surgery and special care must be taken after it... These patients are usually admitted to the NCCU for one or two days, and their heart rhythm is controlled with a device, and an oxygen mask is placed between these brain surgeries, but absolute recovery is required after this. 3 and 10 days..
