There is no definition of “light” or “heavy” cancer. Glioma, commonly known as glioma, is the most common malignant tumor in the skull. Glioma is a collective term for tumors of glial cells and neuronal cells of the nervous system. It is the most common malignant tumor inside the brain, i.e., intracranial, and is mostly caused by factors such as heredity, electromagnetic radiation, and viral infections, etc. Patients often suffer from headache, nausea and vomiting, epilepsy, and blurred vision, among other typical clinical symptoms. Glioma can be classified into astrocytoma, glioblastoma and oligodendroglioma according to different cell types, and the treatment and prognosis of different types of glioma are also different, and the treatment methods include surgery (e.g., craniotomy for gliomas), medication (e.g., temozolomide), radiotherapy, and chemotherapy. It is recommended that if patients are diagnosed with glioma, they should undergo treatment under the guidance of doctors in a timely manner and maintain an optimistic and positive attitude.
