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.
“He said just to be safe he would get me an MRI scan on April 18 which I went to. He assured me again it was just precaution and they most likely wouldn’t find anything.
“It was just to rule it out basically.
“I was told I have two brain tumors – a large one on the right side of my head which was described as the size of a tennis ball and another smaller one the size of a squash ball in the middle.
“I was later told the bigger one might have been growing for 20 years and only now it has gotten so big it was pushing my brain and causing symptoms
