The signs and symptoms of glioblastoma are initially non-specific and conclude as a headache, nausea, vomiting, and drowsiness. These malignant tumours create pressure inside the brain, which is the earliest visible symptom. Based on the location and severity or stage of the tumour, a variety of other symptoms can also be viewed. This includes: Weakness and Fatigue. Loss of memory. Speech difficulties. Reduced mobility, especially on one side of the body. Seizure. Visual impairment.DFDAFF
The exact cause and trigger of GBM tumours are not clear. However, brain tumours will continue to grow if left untreated. Without treatment, the damage caused may be fatal and claim life, if severe. Some factors that can cause GBM tumour are: Genetic factors and family history. HIV infections. Exposure to harmful radiations. Unhealthy lifestyle or eating habits, along with the habit of smoking, which multiply the risks.
The diagnosis of the disease begins with a brief of the patient’s medical history. the doctor might ask questions about your past illness, family history, existing symptoms and their duration, and their severity. A neurological examination can further assist doctors in the diagnosis. A close look at the tumour tissue can help confirm if it is glioblastoma or not. After the sample is taken, the doctor examines it under the microscope. Imaging tests conducted to identify location and size of the tumour are: Magnetic Resonance Imaging (MRI) Computed Tomography (CT) scan Positron Emission Tomography (PET) scans Magnetic Resonance Spectroscopy (MRS), a brain scan that monitors biochemical processes inside the brain
There is no definite cure for the disease. The available treatments aim to provide relief from pain and symptoms, improving the quality of life and survival. Surgery, radiation therapy, or chemotherapy may be advised depending on the patient’s health and medical stability. Surgery The goal of surgery is to carefully remove the tumour and affected the skin. It aims to restrict the tumour from spreading further. This is the first step for treatment, and the tissue extracted can be tested under the microscope to confirm glioblastoma diagnosis. Radiation Therapy After the surgery, radiation therapy is performed. An external beam of radiation is focused or pointed on the affected area to kill the cancerous cells. Proton therapy, interstitial radiation, or brachytherapy are some of the common radiation therapies used for treatment. The procedure reduces the chances of damage to surrounding brain tissues. Chemotherapy Chemotherapy uses drugs to deactivate the cancerous cells and stop their growth. The drugs can either be given orally or injected directly. The treatment destroys cancerous cells and prevents their reproduction.
Some risks of GBM tumour are: Depression. Insomnia. Brain swelling. Spreading of tumour. Recurrence.
