When 63-year-old John Starns slumped on a train station bench in Sevenoaks, drenched in sweat and struggling to stay upright, most passers-by assumed he was drunk. He looked wobbly, pale, and visibly disoriented. But what looked like an awkward case of public intoxication turned out to be something far more sinister: a brain tumour hiding behind symptoms commonly mistaken for vertigo. From “It’s Just Vertigo” to “You Have a Brain Tumour”Initially told he had vertigo, John tried to carry on with his life. But as the months passed, his dizziness became more intense and debilitating. At their worst, the episodes forced him to lie down, eyes shut, until the world stopped spinning. Still, no one suspected the real cause.Three months and one MRI scan later, John finally got the truth. He reportedly had a vestibular schwannoma, a rare, benign brain tumour sitting on the nerve that connects the brain to the inner ear. It was affecting his balance, hearing, and overall coordination, symptoms that, in hindsight, were never typical of garden-variety vertigo.What is Vestibular Schwannoma?Despite the intimidating name, a vestibular schwannoma is not cancerous. It develops slowly over time from Schwann cells, the fatty insulation on your nerves. In this case, the tumour formed on the vestibulocochlear nerve, which governs both hearing and balance.That is why the symptoms can masquerade as something much less serious. Dizziness or vertigoHearing loss in one earRinging or buzzing sounds (tinnitus)Poor sound localisationIn more advanced cases, numbness on one side of the faceBecause these tumours grow at a glacial pace, symptoms tend to hide for months or even years. According to Cancer Research UK, they account for around 8 per cent of all brain tumours, with risk increasing significantly after the age of 65. In rare cases, they are linked to a genetic condition called neurofibromatosis, which often causes tumours on both sides of the brain.Why Dizziness Deserves a Second LookMost of us treat dizziness like a mild inconvenience. You get up too fast, feel woozy for a second, then go about your day. Maybe you chalk it up to dehydration, skipping breakfast, or scrolling on your phone in bed for too long. But dizziness could be a sign of something more serious. For John, it was not just one woozy episode. It was a string of unsettling, spin-the-room moments that left him lying flat on his back, eyes squeezed shut, praying for the world to stop pirouetting. And while vertigo was the first suspect, his brain had other plans, like growing a tumour on his vestibulocochlear nerve.That is the thing with dizziness: it is vague, common, and often misunderstood. It can signal anything from low blood pressure and ear infections to neurological conditions that need serious medical attention. But because it is so easy to dismiss and hard to describe without wildly gesturing, it often gets brushed under the rug until it insists on being noticed.If you face dizziness, do not ignore it. Especially if the dizziness is intense, recurrent, or comes with sidekicks like hearing loss, balance issues, or ringing in your ears.
