Tinnitus led to brain tumour diagnosis; patient marks 10-year milestone with fundraising

Darren Harris, a 59-year-old former IT functional analyst from Paignton, Devon, was told he had tinnitus after years of persistent ringing in his ears. What began as a common ear symptom became a life-changing medical journey when routine hearing tests prompted a referral for advanced imaging. In March 2015, scans revealed a stage-one tentorial meningioma at the base of his brain — a slow-growing, non-cancerous tumour that can nonetheless press on nerves and brain tissue, triggering a range of problems from blurred vision and headaches to hearing loss and balance issues.

Meningiomas are typically slow-growing and rarely spread, but their location can make them dangerous if they grow large enough to compress critical structures. Harris underwent a series of tests, including MRIs, before doctors concluded that the tumour was operable only in a very limited way. Faced with the option of limiting or delaying treatment, he chose a cutting-edge approach designed to target the tumour with minimal damage to surrounding brain tissue: gamma knife radiosurgery. The procedure, performed at BMI Thornbury Hospital in Sheffield, uses a helmet-like frame to immobilize the head and delivers more than 300 precisely focused beams of radiation to destroy tumour cells while sparing healthy tissue. The treatment, he noted, was costly and seen as a specialist option for tumours like his, with a price tag of about £35,000. Harris was privately insured, which allowed access to this high-precision treatment that mainstream radiotherapy could not guarantee for his specific location.

The gamma knife procedure has helped many patients, but it is not without risk. In rare cases, radiosurgery can trigger seizures or cause numbness, balance problems, changes in vision or hearing, and fatigue. For Harris, the decade since his initial diagnosis has included ongoing neurological challenges: epilepsy and atrial fibrillation, an irregular heartbeat that clinicians attribute in part to the stress and aftermath of seizures. He has also experienced lingering effects such as visual impairment and numbness down the left side of his body. Yet he emphasizes progress and gratitude for the treatment that stopped the tumour from growing and bought him years of life with his wife, Sharon, and family.

"It was cutting edge," Harris recalled. "They bolted a metal frame to my skull to keep me completely still, mapped the tumour in 3D, and then targeted it precisely. The treatment cost £35,000. Luckily, I had private health insurance, but many families can't afford that."

Now, ten years after his diagnosis, Harris and Sharon have turned their experience into advocacy. The couple hosted a fundraising event for Brain Tumour Research that raised more than £800, underscoring the ongoing need for funding in brain tumour research and the development of new, life-extending therapies. Harris said reaching a decade after diagnosis was something he never expected, and he credits the combination of treatments and the expanding knowledge about brain tumours with his longevity. "I know how incredibly lucky I am to still be here, and that’s only because of the treatments and knowledge we have today," he said. "But too many people aren’t as fortunate, and that’s why funding into brain tumour research is absolutely vital. We need continued investment so that more people can reach milestones like this, and so families in the future have real hope, better treatments, and ultimately, a cure."

Letty Greenfield, Community Development Manager at Brain Tumour Research, praised Harris for sharing his experience. "Darren’s courage and willingness to share his journey helps raise awareness of the need for greater investment in brain tumour research and improved access to life-saving technology," she said. "We hope that Darren’s story inspires others to support our Christmas appeal and to push for better outcomes for people facing brain tumours."

The broader context underscores why stories like Harris’s matter. Tinnitus affects an estimated 7.6 million people in Britain, with about 1.5 million suffering severe symptoms that can dramatically impair daily life. In parallel, UK incidence of meningioma — including tentorial forms like Harris’s — is estimated at 2,000 to 3,000 new cases each year, with women more commonly diagnosed. Treatments vary depending on the tumour’s size and location; while some meningiomas are monitored, others are treated with radiation therapies (including proton therapy) or innovative radiosurgical techniques like gamma knife to control growth and protect surrounding brain tissue. The aim in all cases is to reduce symptoms, preserve function, and extend life, while balancing risks associated with the chosen modality.
