George Wade, 42, from North Yorkshire in the UK, first started experiencing symptoms in March last year.
But, having been for a day at the Cheltenham races, he chalked his symptoms down to having consumed too much alcohol.
On the drive home from the event, he began to suffer from a severe headache, memory loss and nausea when looking at car headlights.
But it wasn’t until the following month that he suffered what he thought was a stroke when the left side of his body became weak and his face started to droop.
George had a number of tests which came back normal, but it was his brother-in-law, Dr Caspar Wood, who booked him in for an MRI scan to make sure everything looked as it should after he – and George’s wife, Ellie – believed he could have experienced a stroke.
Unfortunately, the scan revealed two brain tumors, which left George in complete shock.
“Ellie called Caspar who assumed it may be a stroke,” he said.
“The following day he arranged for me to have a blood and eye test which came back all clear and he assured me I was fine.
