Overview

• Glenn Colmer, 51, endured fatigue, headaches, and dizziness for months before a seizure on February 18 led to a high-grade glioma diagnosis and his death on February 28.
• Early GP visits resulted in glasses and painkillers, delaying proper diagnosis and highlighting gaps in early symptom recognition.
• His family has raised over £3,000 so far and will host a charity golf day on August 1 at Southampton Municipal Golf Course in his honour.
• Brain tumours receive just 1% of the national cancer research budget despite killing more children and adults under 40 than any other cancer.
• Colmer was a beloved sports teacher and mentor at Itchen Sixth Form College, and his legacy now drives renewed awareness and fundraising efforts.
