Does brain tumour surgery treat glioblastoma?

The operation may reduce the amount of tumour pressing on the brain, help with some symptoms, and provide tissue to confirm the diagnosis. Its benefit and feasibility depend on the tumour's position, the brain functions nearby, the person's health, and the goals agreed with the care team.

Glioblastoma tends to grow into surrounding brain tissue, so the boundary between tumour and healthy tissue may not be clearly separable. A neurosurgeon therefore balances removing tumour against preserving movement, language, vision, thinking, and other essential functions. Complete removal of everything visible on a scan does not mean that every tumour cell has been removed.

For some people, a biopsy rather than a larger removal is the safer way to obtain tissue. Laboratory examination confirms the tumour type and may reveal characteristics that guide the next stage of care. Radiotherapy and anti-cancer medicines are commonly considered after recovery to address cells that surgery cannot safely remove.

At the consultation, describe changes in speech, strength, sensation, memory, mood, vision, balance, headaches, or seizures. Take an up-to-date medicine list and highlight blood thinners, seizure medicines, and steroids. The team may need this information to plan the operation, anaesthetic care, and support after discharge.

Clarify whether the proposal is a biopsy or tumour removal, the specific objective, and the functions that could be affected. Ask who will discuss the tissue findings, how rehabilitation needs will be assessed, and when oncology treatment may begin. Follow only the hospital's tailored directions about changing medicines or fasting; do not stop prescribed treatment on your own.

Call emergency services for a first seizure, ongoing or back-to-back seizures without recovery, sudden one-sided weakness, abrupt trouble speaking, collapse, severe confusion, or reduced consciousness. A rapidly intensifying headache with repeated vomiting or new neurological changes also needs urgent assessment because pressure or swelling in the skull can worsen quickly.

During recovery, contact the surgical service promptly about a new or worsening neurological problem, increasing sleepiness, persistent vomiting, fever, spreading redness around the incision, swelling, discharge, or fluid leaking from the wound. Keep the team's contact and emergency instructions readily available to the person helping you at home.

Consider asking: How much tumour do you expect to remove, and what limits that amount? Could surgery change my current symptoms or abilities? What risks relate specifically to this tumour's location? Would a biopsy answer the treatment questions with less risk? How will you manage swelling and seizures? Which rehabilitation specialists might be involved, and how will surgery connect with my next oncology treatment?
