World Brain Tumour Day 2026: 10 Things You Must Know About Brain Tumours

Every year on June 8, the world comes together to observe World Brain Tumour Day  a day first established in 2000 by the German Brain Tumour Association (Deutsche Hirntumorhilfe e.V.) to raise awareness, reduce stigma, and push for better research, diagnosis, and treatment of brain tumours globally.

It is not a day built on fear. It is built on knowledge  because when it comes to brain tumours, what you do not know can genuinely cost you your life.

At Felix Hospitals, we see the difference that early detection makes. We also see what happens when people ignore symptoms for months  or years  because they did not recognise what their body was trying to tell them.

This World Brain Tumour Day 2026, here are 10 things every person should know  ranked by what matters most..

A Brain Tumour Is Not Always Cancer  But It Always Needs Attention

This is perhaps the most important thing to understand, and it changes how people think about the diagnosis entirely.

Brain tumours are broadly divided into two categories  benign (non-cancerous) and malignant (cancerous). Benign tumours do not spread to other parts of the body. But  and this is critical  they can still be life-threatening depending on where they are located in the brain.

A benign tumour pressing against the part of the brain that controls breathing, vision, or movement can be just as dangerous as a malignant one. The brain has no extra space. There is no room to expand.

So when someone says "it is not cancer, you are fine," that is not the complete picture. What matters is location, size, rate of growth, and how quickly the right medical team gets involved.

Brain Tumours Are More Common Than People Think

According to global data, approximately 300,000 people are diagnosed with a primary brain tumour every year worldwide. In India, the incidence is estimated at around 5 to 10 per 100,000 population  and with a population of 1.4 billion, that translates to a significant number of diagnoses annually.

What makes this particularly important is that brain tumours affect people of all ages  from newborns to the elderly. They are, in fact, one of the most common cancers in children. In adults, the incidence increases with age, with the highest rates seen in people above 65.

The fact that brain tumours do not discriminate by age, gender, or lifestyle is exactly why awareness matters  and why no persistent neurological symptom should be dismissed as stress or exhaustion without proper evaluation.

The Warning Signs That Should Never Be Ignored

Brain tumours are deceptive. Many of their early symptoms overlap with far more common, benign conditions: tension headaches, vision problems from screen fatigue, mild personality changes written off as stress. This overlap is precisely why so many people are diagnosed late.

Here are the symptoms that warrant urgent medical evaluation:

• Persistent or worsening headaches  particularly those that are worse in the morning, on lying down, or accompanied by vomiting
• Seizures occurring for the first time in an adult with no prior history of epilepsy
• Gradual vision changes  blurring, double vision, or loss of peripheral vision
• Weakness or numbness on one side of the body
• Difficulty with speech  trouble finding words, slurring, or not understanding what others say
• Memory problems or confusion that are progressively worsening
• Personality or behavioural changes  unexplained mood swings, aggression, or apathy noticed by family
• Loss of balance or coordination
• Nausea and vomiting without a clear gastrointestinal cause

None of these symptoms automatically mean a brain tumour. But any of them  especially if persistent or progressive  should be evaluated by a neurologist without delay.

There Are Over 120 Types of Brain Tumours  Each Behaves Differently

Not all brain tumours are the same, and treatment is never one-size-fits-all. The World Health Organisation classifies brain tumours into more than 120 distinct types, based on the cell of origin, grade, and molecular characteristics.

Some of the most commonly encountered include:

• Gliomas  arising from glial cells; includes glioblastoma multiforme (GBM), one of the most aggressive forms
• Meningiomas  arising from the meninges (the membranes surrounding the brain); often benign and slow-growing
• Pituitary adenomas  tumours of the pituitary gland, which often present with hormonal symptoms
• Medulloblastomas  most common in children; arise in the cerebellum
• Acoustic neuromas (Schwannomas)  benign tumours affecting the nerve connecting the ear to the brain; often presenting with hearing loss
• Craniopharyngiomas  rare tumours near the pituitary; common in children and can affect growth and hormones
• Metastatic brain tumours  originating from cancers elsewhere in the body (lung, breast, kidney, skin) that spread to the brain

Each type responds differently to surgery, radiation, and chemotherapy. This is why the histopathological and molecular diagnosis of the tumour is as important as identifying it on a scan.

Diagnosis: What Happens After the Scan

An MRI showing a suspicious mass in the brain is not the end of the diagnostic process  it is the beginning. Here is what typically follows:

• Step 1  MRI with contrast: A gadolinium-enhanced MRI gives the treating team detailed information about the tumour's size, location, blood supply, and relationship to surrounding brain structures. Functional MRI (fMRI) may also be used to map critical brain regions before surgery.

• Step 2  CT scan: Often used alongside MRI to assess bone involvement or detect calcification within the tumour.

• Step 3  Biopsy or surgical resection: A tissue sample is essential for definitive diagnosis. This is analysed by a neuropathologist to determine the tumour type, grade, and increasingly, molecular markers that guide treatment decisions.

• Step 4  Molecular profiling: Modern neuro-oncology relies heavily on molecular markers  IDH mutation status, MGMT methylation, 1p/19q co-deletion, and others. These not only confirm diagnosis but also predict prognosis and response to specific therapies.

• Step 5  Multidisciplinary team (MDT) review: Neurosurgeons, neuro-oncologists, radiation oncologists, radiologists, and neuropathologists review the case together before a treatment plan is finalised.

At Felix Hospital, this multidisciplinary approach is core to how complex neurological cases are managed. Every patient presenting with a suspicious neurological finding is evaluated through a structured protocol  not a rushed, single-doctor decision.

Treatment Options in 2025: More Than Surgery

Brain tumour treatment has evolved significantly over the last two decades. What was once limited to surgery and radiation now includes a range of modalities that can be combined and tailored to the specific tumour type and patient condition.

Surgery (Craniotomy): For many tumours, surgical removal  or as much removal as safely possible  remains the first line of treatment. Advances in neuronavigation, intraoperative MRI, and awake craniotomy (where the patient is kept conscious to monitor speech and motor function during surgery) have made resections safer than ever.

Radiation therapy: Used after surgery to target remaining tumour cells, or as primary treatment where surgery is not possible. Techniques include whole-brain radiotherapy, stereotactic radiosurgery (Gamma Knife, CyberKnife), and fractionated stereotactic radiotherapy.

Chemotherapy: Temozolomide (TMZ) is the most commonly used chemotherapy for high-grade gliomas. It is often given alongside and after radiation therapy.

Targeted therapy: For tumours with specific molecular profiles, targeted agents that block particular signalling pathways are now part of the treatment landscape.

Immunotherapy: Still largely investigational for brain tumours, but showing promise in certain subtypes, particularly glioblastoma.

Tumour Treating Fields (TTF): A wearable device therapy that uses low-intensity alternating electric fields to disrupt tumour cell division  now approved for glioblastoma.

Rehabilitation: An often underappreciated component of brain tumour care. Physiotherapy, speech therapy, occupational therapy, and neuropsychological support are critical for recovery and quality of life after treatment.

What Causes Brain Tumours? What We Know  And What We Do Not

One of the most distressing aspects of a brain tumour diagnosis  for patients and families alike  is the question: Why did this happen?

In the majority of cases, there is no clear identifiable cause. Unlike lung cancer and smoking, or cervical cancer and HPV, most brain tumours arise without a single definitive risk factor.

What we do know:

• Ionising radiation is the only well-established environmental risk factor  people who received therapeutic radiation to the head (e.g., for childhood leukaemia) have an elevated risk decades later
• Genetic syndromes  including neurofibromatosis type 1 and 2, Li-Fraumeni syndrome, Von Hippel-Lindau disease, and Turcot syndrome  carry an increased risk of brain tumours
• Age  the risk of most brain tumour types increases with age.
• A family history of brain tumours slightly increases individual risk, though most brain tumours are not hereditary

What the evidence does not support:

• Mobile phone or WiFi radiation causing brain tumours  multiple large-scale studies have not established this link
• Artificial sweeteners as a cause
• Head injuries directly causing brain tumours

Understanding what is evidence-based and what is not matters  because misinformation around brain tumours can lead people to make decisions based on fear rather than facts.

Paediatric Brain Tumours: A Special and Urgent Category

Brain tumours are the most common solid tumour in children and the leading cause of cancer-related death in the paediatric population. In children, the tumour types, locations, and treatment approaches differ significantly from adults.

Common paediatric brain tumours include:

• Medulloblastoma (most common malignant brain tumour in children)
• Ependymoma
• Brainstem glioma (diffuse intrinsic pontine glioma  DIPG  one of the most difficult to treat)
• Craniopharyngioma
• Low-grade glioma (often more treatable than the adult equivalent)

Symptoms in children can be subtle and easily attributed to other causes  headaches dismissed as school stress, balance problems written off as clumsiness, declining school performance seen as behavioural rather than neurological.

Parents and teachers should be aware: a child who suddenly develops coordination problems, complains of persistent morning headaches, or shows a rapid decline in academic performance or vision deserves neurological evaluation  not just reassurance.

The Mental Health Dimension of Brain Tumour Care

A brain tumour does not just affect the brain physically. It reshapes the lived experience of the person carrying it  and their family.

Patients frequently report anxiety about recurrence, depression, cognitive changes (often called "chemo brain" or treatment-related cognitive impairment), and a profound sense of uncertainty about the future. Caregivers face their own invisible burden  the emotional exhaustion of supporting someone through a diagnosis and treatment that can stretch over months or years.

Mental health support is not an optional add-on to brain tumour care. It is a core component.

This includes:

• Psychological counselling and psychotherapy for patients and caregivers.
• Support groups  peer connection with others who understand the experience.
• Palliative care involvement early in the treatment journey  not just at end of life, but to support quality of life throughout.
• Clear, honest communication from the medical team about prognosis and treatment options.

At Felix Hospital, every serious neurological diagnosis is approached with an understanding that the person in front of us is not just a scan or a biopsy result. They are someone whose life has just changed  and who needs medical excellence and human support in equal measure.

What You Can Do  Today

World Brain Tumour Day is not just about awareness for others. It is an invitation to act.

• If you have symptoms, get evaluated. Do not self-diagnose with Google. Do not wait for symptoms to worsen. An MRI takes less than an hour. The information it gives your doctor is irreplaceable.

• If someone you know has symptoms, say something. People often dismiss their own neurological symptoms. A gentle, concerned push from someone who cares can be the reason they go to a doctor.

• If you have a family history of brain tumours, discuss genetic counselling. Your personal risk assessment is worth having.

• If you are a caregiver for someone with a brain tumour  ask for help. For yourself. Caregiver burnout is real and well-documented. You cannot support someone else if you are running on empty.

• If you want to contribute, support brain tumour research and advocacy. Patient advocacy organisations, research funding bodies, and hospitals working on trial therapies depend on public engagement and support.
