What should you know about glioblastoma of the brain?

Glioblastoma is a tumour that starts in brain tissue and can affect nearby functions as it grows or causes swelling. Possible effects include headaches, seizures, changes in movement, speech, memory, vision or personality, although symptoms vary with location.

Doctors use neurological examination, brain scans and tumour tissue findings to understand the diagnosis. The care team considers the tumour’s site, what can be reached safely, laboratory findings and your general health.

A multidisciplinary team may discuss brain tumour surgery, radiotherapy and chemotherapy. Surgery may provide tissue for diagnosis and remove accessible tumour, while other treatments address cells that cannot be removed. The plan should include symptom control, seizure advice, rehabilitation and support for daily activities.

Take someone to appointments if helpful, write down changes in symptoms and ask for a clear contact plan. A clinical trial can be considered when its purpose and demands fit your goals.

Call emergency services for a first seizure, seizures that repeat without recovery, sudden weakness, new difficulty speaking, loss of consciousness, severe confusion or a rapidly worsening headache with vomiting. Use your oncology team’s urgent number for new or worsening symptoms that are not immediately life-threatening.
