Gliomas are the most common type of malignant tumor within the skull, and they are also a form of cancer. Cancer is a very broad term essentially describing a process where some cells proliferate abnormally and differentiate without dying, and gliomas proliferate in the same way. To give an analogy, think of a bunch of villains: if there are heroes to suppress and resolve these villains, then generally, people would not develop tumors. However, if this group of villains gradually becomes stronger and defeats the heroes, then these villains gather within the body, forming a tumor. The same principle applies to the formation of cancer. Therefore, for such cases, it is crucial to detect cancer early and begin the appropriate treatment. Early treatment can have some very beneficial effects on the prognosis for the patient.

Principles of Treatment for Glioma

For patients with glioma, the primary treatment method is still to surgically remove the tumor, followed by postoperative radiotherapy, chemotherapy, and other related treatments. The main treatment principle is to detect, diagnose, and treat early. During surgery, the tumor should be removed as completely as possible, and it is advisable to receive postoperative radiotherapy and chemotherapy early to effectively consolidate the surgical treatment effects. This helps to kill tumor cells to the greatest extent, slow down the probability and timing of tumor recurrence, and extend the patient's lifespan as much as possible. Therefore, for patients with glioma, it is recommended to choose to seek surgical treatment at well-known, top-tier hospitals locally.

Is glioma a terminal illness?

Glioblastoma is not an incurable disease. Patients with glioblastoma have a type of malignant tumor that tends to grow rapidly. These tumors often adhere to surrounding brain tissue in the early stages, making complete surgical removal difficult. If any glioma cells remain after surgery, the tumor tissue will gradually grow over time. Thus, patients with glioblastoma are prone to recurrence, but it is not an incurable disease. If early detection and surgical removal can be achieved, and supplemented by radiotherapy and chemotherapy, it can maximize the therapeutic effects of the surgery, thereby effectively improving the prognosis and delaying the progression of the disease. This approach can relatively extend the patient's lifespan, and some patients may even achieve long-term survival.

Glioma Symptoms

For patients with glioma, they often exhibit certain degrees of headache and dizziness, with headaches typically located bilaterally in the frontal or temporal regions. The nature of the pain is relatively sharp, manifesting as intermittent attacks that progressively worsen over time. Long-standing gliomas easily induce a notable increase in intracranial pressure, presenting with severe headaches, nausea, vomiting, and even a decrease in vision or visual field defects. When the glioma is located in the parietal lobe and affects important motor function areas, it can lead to unilateral or bilateral limb weakness, numbness, pain, and possibly even trigger hemiplegia.

Treatment of brain glioma

For patients with brain gliomas, it is recommended that they visit a local hospital as soon as possible in the early stages of the disease. A physician with extensive surgical experience should help assess the current situation through cranial CT, cranial MRI, and enhanced cranial MRI scans, to determine the location, scope, and range of edema of the glioma, as well as its proximity to surrounding blood vessels and nerves, and to establish a personalized surgical treatment plan. Through surgery, the glioma in the brain should be removed as completely as possible. After surgical treatment, most patients can achieve satisfactory outcomes. However, since gliomas are malignant tumors, it is necessary to follow up surgery with early radiation and chemotherapy treatments.

Clinical manifestations of glioma

For patients with glioma, as it is a malignant tumor with a rapid growth rate, they may exhibit severe symptoms at the early stage of the disease, including severe headaches, dizziness, nausea, vomiting, loss of appetite, poor mental state, poor sleep quality at night, frequent insomnia and nightmares, and easy waking up. As the tumor increases in size, it often causes an increase in intracranial pressure. In severe cases, this may lead to optic disc edema, decreased vision, and visual field defects. Additionally, some patients may experience impairment in motor functions, manifesting as hemiplegia, and in some cases, aphasia. It is advised to undergo surgery in the early stages, followed by radiotherapy and chemotherapy.
