What is glioblastoma?
Glioblastoma is an aggressive cancerous tumor that develops in the brain. It can grow quickly and invade nearby tissue. Treatment may help slow its progression and manage symptoms, but a cure is not currently available.
Symptoms vary and can include worsening headaches, seizures, nausea, changes in vision, and changes in thinking, behavior, or movement. Symptoms alone do not establish a diagnosis.
How is it evaluated and treated?
Doctors may use neurological exams, MRI scans, and tissue testing to diagnose the condition. Treatment options can include surgery when feasible, radiation, chemotherapy, and other specialist-directed approaches, including clinical trials.
