Brain Tumour Surgery in Malaysia

A brain tumour diagnosis changes everything in an instant. As a neurosurgeon, I’ve sat across from hundreds of patients and families at that exact moment. What I’ve learned is this: what happens in the next 72 hours — the decisions made, the specialist seen — matters enormously.

This page is written for you. Not for other doctors. For the person who just received a diagnosis, or the family member searching at midnight trying to understand what comes next.

What Is a Brain Tumour?

A brain tumour is an abnormal growth of cells within the brain or its surrounding structures. Tumours are classified in two fundamental ways:

By origin:

• Primary — begins in the brain itself (glioma, meningioma, medulloblastoma)
• Secondary (metastatic) — spreads to the brain from cancer elsewhere in the body (lung, breast, colon)

By behaviour:

• Benign — non-cancerous, grows slowly, rarely spreads
• Malignant — cancerous, grows faster, may invade surrounding tissue

The grade (I–IV) reflects how aggressive the tumour is. Grade I meningiomas are often curable with surgery alone. Grade IV glioblastomas require a combined approach of surgery, radiation, and chemotherapy.

Critically: benign does not mean harmless. A benign tumour in the wrong location — pressing on the brainstem, the optic nerve, or the motor cortex — can be life-threatening. Location matters as much as biology.

Types of Brain Tumours I Treat

Meningioma

The most common primary brain tumour in adults. Arises from the meninges — the protective membrane surrounding the brain. Usually benign (Grade I), slow-growing, and highly curable with surgery when detected early.

Glioma & Glioblastoma (GBM)

Tumours arising from glial cells — the support cells of the brain. Ranges from low-grade (Grade II) which may be watched or treated conservatively, to glioblastoma (Grade IV), the most aggressive primary brain tumour. Treatment requires surgery plus adjuvant therapy.

Medulloblastoma

The most common malignant brain tumour in children. Arises in the cerebellum (back of the brain). Highly treatable with modern multimodal therapy. Early surgery for maximal safe resection is the cornerstone of care.

Pituitary Tumours (Adenoma)

Located at the base of the brain, pituitary adenomas affect hormone regulation. Most are benign. Many can be removed through minimally invasive endonasal (through-the-nose) surgery — no external incision required.

Acoustic Neuroma (Vestibular Schwannoma)

A benign tumour growing on the nerve connecting the inner ear to the brain. Causes progressive hearing loss, tinnitus, and balance problems. Managed with surgery, radiosurgery, or watchful waiting depending on size and growth rate.

Brain Metastases

Cancer that has spread to the brain from elsewhere in the body. Requires a multidisciplinary approach — neurosurgery for resection or biopsy, combined with oncology input. Surgical removal can dramatically improve quality of life and survival.

Symptoms: When Should You See a Neurosurgeon?

The brain has no pain receptors. Tumours cause symptoms by pressure — on brain tissue, on nerves, or by blocking cerebrospinal fluid.

See a neurosurgeon if you experience:

• Persistent or progressively worsening headaches — especially on waking
• New-onset seizures at any age
• Unexplained weakness or numbness in an arm, leg, or one side of the face
• Vision changes: blurring, double vision, loss of peripheral vision
• Speech difficulty — slurring, word-finding problems
• Memory or personality changes
• Loss of balance or coordination
• Nausea and vomiting without gastrointestinal cause

Red flags requiring urgent evaluation:

• Sudden severe headache (“thunderclap” — the worst of your life)
• Seizure with no prior history
• Rapid neurological deterioration over hours to days

How Brain Tumours Are Diagnosed

MRI Brain with Contrast

The gold standard. A gadolinium-enhanced MRI provides high-resolution imaging of the tumour’s location, size, and relationship to critical brain structures. This is what I review before every surgical consultation.

CT Scan

Faster than MRI, useful in emergencies to detect acute bleeding, hydrocephalus, or calcification within a tumour.

MR Spectroscopy & Functional MRI (fMRI)

Advanced imaging that maps brain metabolism and identifies eloquent cortex — the areas responsible for speech, movement, and memory. Essential for surgical planning near these regions.

Biopsy / Histopathology

The only definitive way to establish tumour type and grade. In many cases, the biopsy is performed at the time of surgical resection. For inaccessible lesions, stereotactic needle biopsy can be performed with precision using frameless navigation.

Molecular Testing

Modern neuro-oncology requires molecular profiling — IDH mutation status, MGMT methylation, 1p/19q codeletion. These markers predict prognosis and guide treatment decisions beyond what the microscope alone can tell us.

Surgical Approaches I Use

Craniotomy with Neuronavigation

The standard approach for most supratentorial (above the tentorium) tumours. A section of skull is temporarily removed to access the tumour under surgical microscope guidance, with real-time 3D neuronavigation — the neurosurgical equivalent of GPS.

Awake Craniotomy

For tumours near eloquent cortex — speech, language, motor function. The patient remains awake during the critical resection phase, able to speak and respond. This allows me to map the functional boundary in real time and remove as much tumour as safely possible without causing permanent deficit.

I have performed awake craniotomies at the University of Malaya Medical Centre and continue to offer this technique for appropriate candidates.

Endoscopic Surgery

Minimally invasive access through natural corridors — the nose for pituitary and skull base tumours, or through small keyhole incisions. Shorter recovery, no external scar.

Posterior Fossa Surgery

Access through the back of the skull for cerebellar tumours, brainstem lesions, and medulloblastoma. Requires detailed knowledge of posterior fossa anatomy and cranial nerve preservation.

Frameless Stereotactic Navigation

All my craniotomies use intraoperative navigation. The patient’s pre-operative MRI is uploaded into the navigation system, allowing me to track instrument position in real time relative to the tumour and surrounding structures.

Intraoperative Neuromonitoring (IONM)

Continuous monitoring of motor evoked potentials (MEP), somatosensory evoked potentials (SSEP), and electromyography during surgery — an early warning system for any traction or thermal injury to eloquent pathways.

What Happens After Surgery

Surgery is almost never the end of the story. What comes after depends on tumour biology.

Multidisciplinary tumour board review is essential. I work closely with neuro-oncologists and radiation oncologists at KPJ Tawakkal to ensure every patient has a coordinated treatment plan, not just a surgical plan.

Recovery: What to Expect

Hospital stay: Typically 3–5 days for elective craniotomy. Longer for complex resections or if post-operative intensive care is needed.

Immediate post-operative phase (Week 1–2): Fatigue, mild headache, scalp tenderness. Most patients are mobilising the morning after surgery.

Early recovery (Weeks 2–6): Return to light activity. Driving is suspended until seizure risk is assessed. Wound review at 2 weeks.

Full recovery (3–6 months): Neurological function continues to improve. Some patients experience temporary weakness, speech difficulty, or cognitive fog that improves with time and targeted rehabilitation.

Long-term follow-up: Regular MRI surveillance — typically at 3 months, 6 months, then annually — is essential to detect recurrence early.

Why Choose an Oxford-Trained Neurosurgeon?

My DPhil at the University of Oxford was not in a clinical specialty. It was in neuroscience — understanding the biology of brain tumours and neuronal repair at a cellular level. I trained under Professor Tipu Aziz and Professor Alexander Green, world leaders in functional neurosurgery.

What this means for you: I bring laboratory-level understanding of tumour biology to the operating theatre. When I decide how aggressively to resect a tumour, or whether to pursue molecular testing before committing to a surgical plan, that decision is informed by both clinical experience and deep scientific knowledge.

Frequently Asked Questions

Q: My MRI shows a brain tumour. Do I definitely need surgery? Not necessarily. Some tumours — small meningiomas, low-grade gliomas in elderly patients, certain acoustic neuromas — can be safely observed with serial imaging. Others require urgent surgery. The decision depends on tumour type, size, rate of growth, symptoms, and your overall health. I’ll be honest with you about which category you fall into.

Q: What is the risk of surgery affecting my speech or movement? The risk is real but quantifiable. Using neuronavigation, intraoperative monitoring, and awake craniotomy where appropriate, modern neurosurgery minimises this risk significantly. I will give you a specific, honest risk estimate based on your tumour’s location before any procedure.

Q: Can I get a second opinion? Yes — and I encourage it for any brain tumour diagnosis. A second opinion is not an insult to your current doctor. It is the right thing to do for a decision of this magnitude.

Q: How quickly do I need to decide about surgery? It depends entirely on the tumour. A rapidly expanding GBM may warrant surgery within days. A small incidental meningioma can wait weeks for a thorough work-up and second opinion. I will tell you clearly which timeline applies to your situation.

Q: Does insurance cover brain tumour surgery in Malaysia? Most major medical insurance plans in Malaysia cover surgical treatment of brain tumours. I recommend contacting your insurer before the consultation so we can plan accordingly. The clinic team can assist with pre-authorisation paperwork.

Q: Is KPJ Tawakkal equipped for complex brain tumour surgery? Yes. KPJ Tawakkal Specialist Hospital is equipped with advanced MRI and CT imaging, dedicated neurosurgical theatres with intraoperative navigation, neuromonitoring capabilities, and a dedicated neurological ICU. Complex cases also have access to intraoperative MRI facilities through our specialist network.

Book a Consultation

If you or a family member has received a brain tumour diagnosis — or has symptoms that concern you — the first step is a face-to-face consultation and review of your imaging.

I review every MRI personally before seeing a patient. Come prepared with your scans on a CD or USB, your referral letter if you have one, and your questions. There are no foolish questions in my clinic.
