Glioblastoma意思

"Glioblastoma" is a type of brain tumor that originates from the glial cells of the brain and spinal cord. It is the most common and most aggressive form of primary brain tumor in adults. Glioblastomas are classified as grade IV tumors according to the World Health Organization (WHO) grading system for brain tumors, which means they are fast-growing and have a high tendency to invade surrounding brain tissue.

Symptoms of glioblastoma can vary widely depending on the location of the tumor in the brain, but they can include headaches, seizures, changes in personality or mental function, difficulty speaking or understanding language, paralysis or weakness in one part of the body, and changes in vision or hearing.

Treatment for glioblastoma typically involves a combination of surgery to remove as much of the tumor as possible, followed by radiation therapy and chemotherapy. Despite aggressive treatment, glioblastomas are often difficult to treat successfully due to their invasive nature and propensity to recur.
