Glioblastoma is a type of brain cancer that arises from glial cells, which support and protect nerve cells. It is known for its aggressive nature and rapid growth, making it one of the most challenging brain tumors to treat. Symptoms can include headaches, seizures, and changes in personality or cognitive function, depending on the tumor's location in the brain. Treatment options for glioblastoma typically involve a combination of surgery, radiation therapy, and chemotherapy. Despite these interventions, the prognosis remains poor, with a median survival time of about 15 months after diagnosis. Ongoing research aims to find more effective therapies and improve patient outcomes.
