How to tell if your headache is a migraine or a brain tumour symptom

The brain serves as the body's control centre, making it arguably the most vital organ in the human body. It is little wonder, then, that any disorder associated with it tends to trigger immediate concern.

Headaches are an almost universal experience, but when they become frequent, many people find their thoughts turning to the most alarming possibility: a brain tumour.

"In reality, most recurrent headaches are migraines, but the overlap in symptoms can make the distinction confusing," Dr Luv Bansal, senior consultant neurologist at Yashoda Medicity, told HT Lifestyle ahead of World Brain Tumour Day 2026.

"Clinically, however, the two conditions differ in pattern, progression, and neurological impact in ways that are usually quite consistent."

Dr Bansal outlined the distinguishing features of each condition to help patients and readers understand the difference.

How to recognise a migraine

According to Dr Bansal, migraines are a primary headache disorder, meaning they stem from changes in brain activity rather than any structural abnormality.

"It typically presents as episodic attacks of throbbing or pulsating pain, often on one side of the head, and may last from four to 72 hours," he stated.

Migraines are commonly accompanied by associated features, which include nausea, sensitivity to light or sound, and visual aura — such as flashing lights, zigzag patterns, or temporary blind spots.

"Importantly, migraines tend to follow a predictable pattern for an individual. Between attacks, neurological examination is normal," shared the doctor.

How brain tumour headaches differ

A brain tumour, by contrast, is a structural lesion that generates symptoms through pressure, invasion, or disruption of brain tissue, Dr Bansal explained. The nature of the headaches it produces is markedly different from those associated with migraine.

"Headache when present is often progressive rather than episodic. It may be worse in the morning, aggravated by coughing or straining, and gradually increases in frequency or intensity over weeks to months," shared the neurologist.

"Unlike migraine, tumour-related headaches are more likely to be accompanied by persistent neurological deficits such as weakness on one side, speech difficulty, personality changes, or seizures appearing for the first time in adulthood."

Further warning signs that may indicate raised intracranial pressure — sometimes caused by a tumour — include vomiting without prior nausea, particularly in the morning, and papilloedema, which refers to swelling of the optic disc visible during an eye examination.

Whilst migraines can also cause vomiting, they rarely produce persistent neurological abnormalities or symptoms that worsen steadily over time, the neurologist noted.

When to seek medical evaluation

"The most important clinical distinction lies in evolution: migraine fluctuates, while tumour symptoms progress. Neuroimaging, such as MRI, is reserved for cases where red flags exist, such as new-onset headaches after age 50, sudden change in headache pattern, neurological deficits, or seizures," he added.

Dr Bansal concluded with a reassuring note for those prone to anxiety about their symptoms.

"While fear often drives assumptions, the reality is reassuring: migraine is far more common, and brain tumours are rare. Yet persistent, changing, or atypical headaches deserve medical evaluation, not because they are likely to be dangerous, but because the stakes, when they are, are too important to ignore."
