Brain cancer is one of the most frightening diagnoses a person or a family can receive. In a single moment, everything changes. Questions flood in faster than answers can come. What exactly is happening inside the brain? Is it treatable? How serious is it? Where do we go from here?
If you or someone you love has been told they have a brain tumour or brain cancer — this guide is written for you. Not in complicated medical language. Not in terminology that only doctors understand. In plain, honest language that gives you the information you need to understand what is happening and what your options are.
Brain cancer is serious. But it is also a condition where treatment has advanced enormously in the past decade. Bangalore is home to some of India’s finest neurosurgeons and oncologists — and getting the right treatment at the right hospital can make an enormous difference to outcomes.
Let us start from the very beginning.
What Is Brain Cancer? (And How Is It Different From a Brain Tumour?)
This is one of the most common points of confusion — and it is important to understand the difference clearly.
A brain tumour is an abnormal growth of cells in or around the brain. Tumours can be either benign (non-cancerous) or malignant (cancerous).
Brain cancer specifically refers to malignant tumours — those that are cancerous, grow aggressively, and can invade surrounding brain tissue.
Think of it this way: all brain cancers are brain tumours — but not all brain tumours are brain cancers. A benign meningioma, for example, is a brain tumour but not brain cancer. A glioblastoma, on the other hand, is both a brain tumour and brain cancer.
This distinction matters because the treatment, prognosis and urgency are very different depending on whether the tumour is benign or malignant.
According to the World Health Organization, brain tumours affect between 40,000 and 50,000 people in India every year. — with 20% of those cases involving children.
Primary vs Secondary Brain Cancer — What Is the Difference?
Primary Brain Cancer
Primary brain cancer originates inside the brain itself. The cancer starts in the brain cells and grows within the brain. Examples include glioblastoma, astrocytoma and medulloblastoma.
Secondary (Metastatic) Brain Cancer
Secondary brain cancer starts somewhere else in the body — most commonly the lungs, breast or skin (melanoma) — and then spreads (metastasises) to the brain through the bloodstream.
Secondary brain cancer is actually more common than primary brain cancer. When cancer has spread to the brain from another part of the body, the treatment approach is different and the primary cancer must also be managed.
Types of Brain Cancer — A Simple Guide
Glioma
The most common type of primary brain cancer. Gliomas arise from the glial cells — the supporting cells of the brain. There are several subtypes:
- Astrocytoma — arises from star-shaped cells called astrocytes
- Oligodendroglioma — arises from cells that produce the myelin coating on nerve fibres
- Ependymoma — arises from cells lining the fluid-filled spaces of the brain
Glioblastoma Multiforme (GBM)
The most aggressive and most common malignant brain tumour in adults. It is a Grade 4 glioma — the highest and most dangerous grade. GBM grows rapidly and is one of the most challenging cancers to treat.
Meningioma
Develops from the meninges — the protective membranes surrounding the brain and spinal cord. Most meningiomas are benign and grow slowly. They are more common in women and in older adults.
Medulloblastoma
A fast-growing tumour that arises in the cerebellum — the part of the brain that controls balance and coordination. It is the most common malignant brain tumour in children.
Pituitary Adenoma
Develops in or around the pituitary gland at the base of the brain. Most are benign but they can disrupt hormone production significantly.
CNS Lymphoma
A rare type of brain cancer where lymphoma cells invade the brain. It has been linked to the Epstein-Barr virus (EBV) and is more common in people with weakened immune systems.
Brain Tumour Grades — What Grade 1, 2, 3, 4 Means
The World Health Organisation (WHO) classifies brain tumours into four grades based on how aggressive and abnormal the cells look under a microscope:
| Grade | Cell Appearance | Growth Speed | Treatment Outlook |
|---|---|---|---|
| Grade 1 | Nearly normal cells | Very slow | Long-term survival very likely |
| Grade 2 | Slightly abnormal | Slow but may recur | Good with treatment |
| Grade 3 | Clearly abnormal, actively dividing | Moderate to fast | Requires aggressive treatment |
| Grade 4 | Most abnormal, chaotic | Very fast, invasive | Most difficult to treat |
Glioblastoma is always Grade 4. Most meningiomas are Grade 1 or 2.
Warning Signs — Symptoms of Brain Cancer
Symptoms of brain cancer vary significantly depending on where in the brain the tumour is located, how large it is, and how fast it is growing. This is why brain cancer symptoms are sometimes misdiagnosed as migraines, stress or vision problems in the early stages.
General Warning Signs
- Persistent, worsening headaches — especially in the morning or that wake you from sleep
- Nausea and vomiting — particularly without an obvious cause
- Unexplained seizures — a new seizure in an adult with no previous history is a medical emergency
- Extreme fatigue — a heaviness that does not improve with rest
Neurological Warning Signs
- Changes in vision — blurred vision, double vision, loss of peripheral vision
- Difficulty speaking or understanding speech
- Memory problems, confusion and difficulty concentrating
- Personality or behaviour changes that family members notice
- Loss of balance and coordination
- Weakness or numbness on one side of the body
- Difficulty swallowing
Warning Signs in Children
- Persistent nausea and vomiting for more than two weeks
- Unusual head growth in infants
- Balance problems and frequent falls
- Changes in school performance or behaviour
- Vision changes — squinting, eye crossing
Important: These symptoms can also be caused by many other conditions. Having one or more of these symptoms does not mean you have brain cancer — but it does mean you should see a doctor promptly for proper evaluation.
What Causes Brain Cancer?
This is one of the most difficult questions in oncology — because in most cases, there is no clear, single cause. There are no known reasons why certain brain cells turn cancerous.
However, research has identified several risk factors that increase the likelihood of developing brain cancer:
Known Risk Factors
Radiation Exposure Exposure to ionising radiation — including previous radiotherapy to the head, high levels of X-ray exposure, or working in strong electromagnetic fields — increases the risk of brain tumours.
Genetics and Family History Less than 5% of brain tumours are caused by hereditary genetic factors. However, having a close relative — parent or sibling — with a brain tumour slightly increases your risk.
Genetic Syndromes Certain inherited conditions significantly raise the risk of brain tumours, including Von Hippel-Lindau disease, neurofibromatosis (Type 1 and Type 2), Li-Fraumeni syndrome, tuberous sclerosis, Cowden syndrome and Lynch syndrome.
Chemical Exposure Long-term exposure to harmful chemicals including rubber, pesticides, solvents and vinyl chloride has been associated with increased brain cancer risk.
Viral Infections The Epstein-Barr virus (EBV) raises the risk of central nervous system (CNS) lymphoma.
Age Risk of most brain tumours increases with age, though brain cancer can and does occur at any age — including in children and young adults.
Metastasis Cancer that has already spread from another primary site — most commonly lung cancer, breast cancer and melanoma — can travel to the brain.
How Is Brain Cancer Diagnosed?
Early and accurate diagnosis is critical. The diagnostic process typically begins with a detailed neurological examination — assessing reflexes, coordination, memory, vision and speech. This is followed by imaging and, in most cases, a biopsy.
Diagnostic Tests and Their Approximate Costs in Bangalore
| Test | Purpose | Approximate Cost |
|---|---|---|
| MRI Scan | Most accurate brain imaging, shows tumour location and size | ₹5,000 – ₹15,000 |
| CT Scan | Initial screening, faster than MRI | ₹3,000 – ₹8,000 |
| PET-CT Scan | Staging, detecting spread | ₹15,000 – ₹25,000 |
| Biopsy | Confirms cancer type and grade | ₹10,000 – ₹25,000 |
| Lumbar Puncture | Detects cancer cells in cerebrospinal fluid | ₹5,000 – ₹10,000 |
| Genetic / Molecular Testing | Guides targeted therapy decisions | ₹20,000 – ₹60,000 |
| Functional MRI | Maps brain functions before surgery | ₹10,000 – ₹20,000 |
| Cerebral Arteriogram | Maps blood vessels around tumour | ₹15,000 – ₹30,000 |
MRI is the most commonly used test to obtain detailed pictures of the various parts of the brain to identify the affected area.
Treatment Options for Brain Cancer in Bangalore
Brain cancer treatment is highly individualised — the approach depends on the type of tumour, its grade, its location, the patient’s age and overall health. Treatment is always planned by a multidisciplinary team of neurosurgeons, oncologists, radiologists and pathologists.
1. Surgery (Craniotomy / Neurosurgery)
Surgery is the primary treatment for most brain tumours. The goal is to remove as much of the tumour as safely possible while preserving brain function.
Types of brain tumour surgery:
- Craniotomy — the most common procedure where part of the skull is temporarily removed to access and remove the tumour
- Minimally Invasive Neuroendoscopy — tumour removal through small holes in the skull, mouth or nose, reaching areas traditional surgery cannot access
- Awake Craniotomy — surgery performed while the patient is conscious under local anaesthesia, used when the tumour is near critical areas controlling speech or movement. This allows the surgical team to monitor and preserve these functions in real time
- Stereotactic Biopsy — image-guided needle biopsy to collect a tissue sample without open surgery
2. Radiation Therapy
High-energy radiation destroys cancer cells. Used after surgery to target remaining cancer cells, or as a standalone treatment when surgery is not possible.
Advanced radiation techniques available in Bangalore:
- External Beam Radiation Therapy (EBRT) — conventional radiotherapy
- Stereotactic Radiosurgery — CyberKnife, Gamma Knife, TrueBeam — delivers highly focused radiation beams to the tumour with extreme precision, without incision
- TomoTherapy — rotating radiation delivery that spares surrounding healthy brain tissue
- Brachytherapy — radioactive implants placed directly near the tumour
3. Chemotherapy
Medications that destroy cancer cells throughout the body. The most commonly used chemotherapy drug for brain cancer is Temozolomide (TMZ) — often given alongside radiation therapy for glioblastoma. Chemotherapy can be administered as tablets or through an IV drip.
4. Targeted Therapy
Drugs designed to target specific molecular characteristics of cancer cells without harming healthy tissue. Particularly useful for tumours with specific genetic mutations identified through molecular testing.
5. Immunotherapy
Immunotherapy harnesses the body’s own immune system to recognise and fight cancer cells. This is one of the most exciting and rapidly advancing areas in brain cancer treatment. It represents a promising frontier, offering the potential for long-lasting remission and enhanced survival rates.
6. Tumour Treating Fields (TTF)
A relatively new treatment using painless electric pulses to stop cancer cells from dividing and multiplying. The device resembles a swim cap connected to a small backpack and is worn continuously. It is used alongside chemotherapy for glioblastoma.
7. CAR-T Cell Therapy
One of the most advanced forms of cancer immunotherapy — available at select centres including HCG in Bangalore. A patient’s own T-cells (immune cells) are genetically engineered to recognise and attack brain cancer cells.
8. Rehabilitation
After surgery and treatment, many patients benefit from physiotherapy, speech therapy and occupational therapy to recover lost functions and return to daily life as fully as possible.

Survival Rates — What the Numbers Mean
Survival statistics for brain cancer depend heavily on the type, grade, location and the patient’s age and overall health. Numbers should always be understood in the context of an individual patient’s specific situation.
| Tumour Type | 5-Year Survival Rate |
|---|---|
| Benign tumours (e.g. meningioma) — complete removal | 85–95% |
| Low-grade gliomas | 40–70% |
| High-grade gliomas | 10–20% |
| Glioblastoma Multiforme (GBM) | 5–10% |
For benign tumors, the cure rate for complete surgical resection is 90% to 100%. For glioblastoma, the most aggressive malignant brain tumour, treatment focuses on prolonging survival and maintaining quality of life. Some patients with low-grade gliomas live with the condition for many years.
These statistics represent averages across large populations. Individual outcomes can and do vary significantly — which is why early diagnosis, the right treatment centre and an experienced multidisciplinary team matter so much.

Frequently Asked Questions
Q: What is the difference between a brain tumour and brain cancer? A brain tumour is any abnormal growth in the brain — benign or malignant. Brain cancer specifically refers to malignant (cancerous) tumours that can invade surrounding tissue and, in some cases, spread. Not all brain tumours are cancerous.
Q: What are the very first signs of brain cancer? The earliest signs are often persistent morning headaches, unexplained nausea, and subtle changes in vision or memory. A first-time seizure in an adult with no prior history is one of the most important warning signs and requires immediate medical evaluation.
Q: Is brain cancer hereditary? Less than 5% of brain cancers are caused by inherited genetic factors. Most cases have no clear hereditary cause. Certain rare genetic syndromes do increase the risk significantly.
Q: Can brain cancer be cured? Some brain cancers — particularly benign tumours and low-grade tumours caught early and completely removed — can be cured. High-grade malignant tumours like glioblastoma are more difficult to cure, but treatment can extend survival and significantly improve quality of life.
Q: How long does brain cancer treatment take? Surgery takes 4–6 hours. Post-operative radiation therapy typically runs for 4–6 weeks. Chemotherapy may continue for several months. The full treatment journey varies from a few months to over a year depending on the type and grade of tumour.
Q: Is brain cancer surgery safe? Brain surgery carries risks including speech difficulties, muscle weakness, coordination problems and balance issues. However, in experienced hands at top neurosurgical centres, these risks are carefully managed. The risks of not treating a malignant brain tumour are always higher than the risks of surgery.
Q: Can brain cancer come back after treatment? Brain cancer is prone to recurrence, particularly high-grade tumours like glioblastoma. Whether a tumour will return depends on factors like its type, grade, how completely it was removed and the patient’s overall health. Regular follow-up imaging is essential after treatment.
Q: What is awake brain surgery and is it really done in Bangalore? Yes. Awake craniotomy — brain surgery performed while the patient is conscious — is available at leading hospitals in Bangalore including Fortis. It is used when the tumour is near areas controlling speech or movement. The patient is kept comfortable but conscious so the team can monitor brain function in real time during the operation.
Q: How do I find the right brain cancer specialist in Bangalore? Doctor Visit Bangalore can help you find the most experienced neurosurgeon or neuro-oncologist in Bangalore based on your specific type and grade of tumour. We help you compare hospitals, get second opinions and book confirmed appointments quickly.
