World Brain Tumour Day: Mistaken for stress? 5 warning signs often missed

We all get headaches. Most of the time, all you need is a couple of paracetamol tablets, a glass of water, and a good night's sleep. But when the words “brain tumour” enter a conversation, most people picture the same thing: a crushing, unmistakable pain that would stop anyone in their tracks.

That picture, as comforting as it feels, is wrong, and that assumption quietly costs people precious time.

It’s a misconception that a brain tumour presents with a severe headache. Headache is a poor predictor of brain tumour; patients with a tumour can present with mild headache or no headache at all.

On World Brain Tumour Day, let’s honestly examine what these symptoms actually look like and why we normalise them for far too long.

The headache that demands attention

By the time a headache from a brain tumour becomes severe, significant time may have already passed since the tumour began growing. The early signs are frustratingly ordinary: a dull ache at the back of the head in the mornings, pressure behind the eyes, a persistent throb that doesn’t quite respond to over-the-counter relief the way it used to.

The difference lies in the pattern. A typical tension headache comes and goes — it responds to rest, hydration, and mild analgesics. A headache linked to raised intracranial pressure tends to be worse in the mornings, upon waking, or when bending forward. It may be accompanied by nausea or vomiting that families dismiss as acidity or indigestion.

A tip to always remember is that any new-onset headache after 50 years of age should not be neglected.

If your headaches are waking you from sleep, changing in character, or are accompanied by vomiting, do not ignore them. If a headache is new, persistent, progressively worsening, or behaves differently from the ones you have had before, it is worth speaking to a doctor, not waiting to see if it passes.

Five symptoms most people miss

Brain tumours are medicine’s great masqueraders. They can look, on the surface, like anxiety, ageing, or plain exhaustion. And because symptoms depend heavily on where the tumour is located and how fast it is growing, no two cases look quite alike.

Brain tumours can present with cognitive change or neurological deficits — speaking difficulty, weakness of limbs, seizures, memory loss, vision or hearing changes, balance issues, or altered sensorium. Symptoms, however, depend on the location and rate of growth of the tumour.

Here are five commonly dismissed symptoms of a brain tumour:

*Recurrent headaches: Frequency and character matter more than intensity. A new type of headache in an adult who rarely experienced it before is a red flag — regardless of how mild it feels.

*Unexplained seizures: A seizure in an adult with no prior history of epilepsy should always be investigated thoroughly. Tumours in certain brain regions can trigger seizure activity long before any other symptom appears.

*Vision changes: Blurred vision, double vision, or a narrowing of the visual field is frequently attributed to eye strain or the need for new glasses. In the context of other neurological symptoms, it can indicate pressure on the optic pathways.

*Memory difficulties and personality changes: Families notice someone seems “not quite themselves” — more irritable, more forgetful, less engaged. It gets chalked up to stress or ageing. In certain tumour locations, these are the earliest and most prominent features.

*Weakness or numbness on one side of the body: Gradual weakening of one hand, clumsiness when walking, or intermittent numbness in a limb are neurological signs that should never be self-diagnosed as “pins and needles” or “a trapped nerve” without proper evaluation.

Impact on children

Paediatric patients can present with hormonal changes along with developmental regression — patterns that are easy to attribute to puberty or behavioural causes, but that warrant careful evaluation.

Parents should be aware that warning signs in children may look very different from those in adults. Hormonal shifts and a regression in developmental milestones such as speech, coordination, or behaviour, and if they find something wrong in that with their child, then a session with the neurologist is worth discussing, particularly when they appear together or without an obvious cause.

Sleep, stress, and your brain

Beyond the clinic, the emerging science matters too, because much of it is within our control. Research over the past decade consistently points to sleep disruption as a factor that puts the brain under significant physiological stress. Poor sleep quality — not just short sleep, but fragmented, non-restorative sleep has been associated with increased inflammatory processes in brain tissue.

Chronic psychological stress compounds this. When the body is in a sustained state of stress, it floods the system with cortisol and other stress hormones that, over time, affect immune surveillance, the body’s ability to detect and destroy abnormal cells before they become a problem.

The advice is unglamorous but evidence-based: protect your sleep. Establish consistent sleep and wake times. Treat insomnia as a medical issue worth addressing. Find sustainable ways to decompress, such as movement, time in nature, creative pursuits, or simply talking to someone.

When to see a doctor

A high index of suspicion is necessary to rule out a brain tumour. Certain brain tumours, if treated early, are curable through surgery, chemotherapy, radiotherapy, or a combination of these.

Many people hesitate to see a doctor over a headache. But a symptom that worries you is a symptom worth discussing. Visit your doctor if your headaches are new and persistent; if you have had any unexplained seizures; if a loved one has remarked with concern that you seem different; if your vision has changed; or if one side of your body is not behaving as it should.

Early detection genuinely changes outcomes. An MRI or CT scan can provide clarity quickly, and if the answer is reassuring, as it very often is, that peace of mind is worth every moment spent in the waiting room.

On World Brain Tumour Day, the ask is simple: stop ignoring the messages your brain is sending you. Pain is not the only language a tumour speaks. Learn to listen for the quieter ones.
