The parents of a young boy who needs cancer treatment in America have set up an appeal for funds.
Seven-year-old Danny King was diagnosed with a brain tumour in April 2011.
His parents Mandy, 41, and Gary, 48, from Tilgate, are taking Danny to Florida for a three month course of daily treatment to stop the tumour growing any larger.
Mandy explained how Danny suffered for weeks before he was diagnosed, aged six.
She said: “He had sickness and diarrhoea one night. For at least eight hours he had excruciating pain.
“I took him to the doctor but at the time there was a sickness bug going around so they put it down to that and it carried on for another nine weeks, one night a week.
“I knew it must be more than a bug. Then one evening when he was in front of the telly he was holding his eye shut and I asked him ‘why are you holding your eye like that?’ and he said, ‘cause that one sees two’.
“I took him to the opticians and he said straight away to go down to the hospital.”
A scan was taken at East Surrey Hospital which found the tumour and fluid on the brain. He was rushed to St George’s Hospital, in London, where he was operated on that night to remove the fluid.
The tumour continued to affect Danny’s memory and movement as it pushed on his nerves.
In November 2012, a scan revealed the tumour was cancerous and it was growing.
It was decided that the best therapy was proton therapy, a type of particle therapy which can be administered very accurately and is not yet available in the UK.
The treatment will involve putting Danny to sleep for three hours every day, five days a week.
The NHS is paying for the flights, accommodation and treatment but Mandy and Gary need to raise around £10,000 for day-to-day expenses and they need to leave money with their 14-year-old son, Billy, who will stay with his adult brother.
