Brain tumour surgery removes abnormal tissue while protecting the healthy brain around it. The commonest approach is a craniotomy — temporarily removing a small window of skull to reach the tumour under a microscope. Smaller or deep tumours may be reached through keyhole or endoscopic routes, and where a tumour sits next to areas that control speech or movement, an awake craniotomy lets the surgeon test those functions live and stop before harm is done.
Two things shape the plan. First, the goal: complete removal where possible, or a safe partial removal plus a biopsy when a tumour is wrapped around vital structures. Second, the tumour type: surgery alone can cure a benign meningioma, whereas an aggressive glioma needs surgery followed by radiotherapy and chemotherapy. Tools like neuronavigation and intra-operative MRI help surgeons remove as much as is safe.
Surgery is considered for tumours causing symptoms or pressure, for those that can be reached safely, and whenever a tissue diagnosis is needed to guide treatment. Some deep or diffuse tumours are better managed with a biopsy followed by radiotherapy rather than an attempt at removal. A neurosurgeon and neuro-oncologist decide together, using your MRI.
A DIFFERENT APPROACH MAY SUIT CLINICAL EVIDENCE
The evidence
What surgery achieves depends almost entirely on the tumour. We give the numbers honestly, benign and malignant alike.
Benign tumours (meningioma)
Complete resectionMeningiomas are the commonest benign brain tumour and are often curable.
Cure with complete removal~90% or higher
Recurrence relates toCompleteness of removal
Glioblastoma — standard care
Stupp regimenFor the commonest aggressive tumour, surgery is the first step of multimodal care.
Standard careSurgery + radiotherapy + temozolomide
Maximal safe removalImproves survival
Extent of removal & survival
GliomaHow much is safely removed affects outcome in malignant glioma.
Gross total resectionBetter PFS & OS
GBM median survival, modern series~15–21 months
The honest picture. Surgery cures many benign tumours outright, but for glioblastoma it buys time and quality of life rather than a cure — the disease almost always returns, and the numbers above reflect that. 1,2 A treatment plan is only as good as the diagnosis behind it, which is one reason a second opinion on the pathology and the plan is worth having.
OUTCOMES
Benefits and limits
WHAT IT CAN DO- Cure many benign tumours with complete removal. 3
- Relieve pressure, seizures and neurological symptoms.
- Give a precise diagnosis to guide the whole treatment.
- Improve survival in malignant glioma as part of multimodal care. 1,2
WHAT IT CANNOT DO- Cure glioblastoma on its own — it needs radiotherapy and chemotherapy.
- Always remove every cell when a tumour hugs vital areas.
- Guarantee no new or recurrent tumour over time.
- Reverse damage a tumour has already done.
SAFETY
Risks and complications
Brain surgery is delicate, and its risks depend on the tumour's location. These are what a neurosurgeon discusses at consent.
Neurological deficit
Weakness, speech or vision changes if the tumour sits near critical areas; awake mapping is used to reduce this risk.
Bleeding & swelling
Managed closely in the ICU in the first days; occasionally needs further intervention.
Seizures
Can occur before or after surgery; anti-seizure medication is used when needed.
Infection & CSF leak
Uncommon; a leak of brain fluid or a wound infection may need treatment.
Your neurosurgeon gives you the full, personalised list at consent. This is a summary, not a complete account.
BEFORE SURGERY
What to prepare for
The imaging, the plan for any treatment after surgery, and the timing of travel are the parts to sort out early.
01Send your MRI and any biopsy
A recent MRI, and any pathology already done, let the team judge whether and how to operate, and plan the safest approach.
02Understand the whole plan
If the tumour may be malignant, ask what radiotherapy or chemotherapy would follow, so you can plan the full course — not just the operation.
03Plan the stay
Surgery and early recovery take about one to two weeks; if radiotherapy follows, a longer stay or a second trip is planned around it.
04The flight home
Long-haul travel too soon after brain surgery is unsafe. The team confirms when it is safe to fly and what to watch for.
05Rehabilitation and follow-up
Physiotherapy, speech or occupational therapy may be needed, and regular MRI scans check for recurrence. We help set up follow-up close to home.
INDICATIVE COST
Cost in India
Surgery package, from$5,000
Typical range$5,000–8,500
Indicative, not a quotation. Malignant tumours needing radiotherapy and chemotherapy cost more overall. India typically saves 70–85% versus the USA or Europe. A current itemised estimate is prepared after clinical review of your records.
Neuro-oncology outcomes depend on a full team — neurosurgery, neuro-radiology, pathology, radiation and medical oncology working together. These are the accredited centres in our network.
FAQ
Questions patients ask
Can a brain tumour be cured by surgery?
Many benign tumours, such as meningiomas, can be cured by complete removal. 3 Malignant tumours like glioblastoma are not cured by surgery alone — it is the first step, followed by radiotherapy and chemotherapy. 1
What is awake brain surgery?
For tumours near speech or movement areas, the patient is woken during surgery so the surgeon can test these functions live and stop before causing harm. It is done under careful anaesthesia and is well tolerated.
Will I need treatment after surgery?
It depends on the pathology. Benign tumours removed completely may need only monitoring; malignant ones usually need radiotherapy and often chemotherapy. The plan is set once the tissue is examined.
How long will I be in India?
Surgery and early recovery take about one to two weeks. If radiotherapy follows, a longer stay or a second trip is planned. We arrange this around your treatment.
Should I get a second opinion first?
For brain tumours it is genuinely worth it. Sending your MRI and any pathology for review confirms the diagnosis and whether surgery, biopsy or another approach is best — before you travel.
Every clinical claim on this page traces to one of these. Where we could not source a figure from peer-reviewed literature, we have left it out rather than estimate it.
1Stupp R, et al. Radiotherapy plus Concomitant and Adjuvant Temozolomide for Glioblastoma.
EORTC/NCIC trial, New England Journal of Medicine, 2005. Established surgery followed by concurrent and adjuvant temozolomide with radiotherapy as standard care; original median overall survival ~14.6 months.
2Real-world glioblastoma resection and Stupp-regimen series.
Multiple single-centre cohorts (e.g. PMC5502175, PMC7348058). Gross total resection is associated with improved progression-free and overall survival; contemporary median OS ~15–21 months.
3Surgical management of intracranial meningioma.
Meningiomas are the commonest benign intracranial tumour; complete (Simpson low-grade) resection offers high cure rates, with recurrence tied to completeness of removal.
