Gliocytoma is a type of brain tumor that arises from glial cells, which support and protect neurons in the central nervous system. It is often considered a low-grade tumor, but its behavior can vary, and it may exhibit aggressive characteristics in some cases. Gliocytomas can lead to various neurological symptoms depending on their location and size, and treatment typically involves surgery, radiation, and sometimes chemotherapy. Due to their origin in glial cells, they can be challenging to treat and may have a tendency to recur.
