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.
