A determined grandmother is raising money to help cure her grandson’s aggressive cancer.

Four-year-old Connor Whipp has neuroblastoma, a rare form of childhood cancer found in children up to the age of five.

His family must raise £250,000 for a treatment currently unavailable in the UK to increases his chances of survival.

Grandmother Mary Power, 51, who works for the accident and emergency unit at Kingston Hospital, has been on compassionate leave visiting London football grounds with a collection box on most match days.

She said: "There’s no other option but to raise the money. I want to see him grow up and fall in love and be happy – I just want to have a bit of his wedding cake."

Connor dubbed Captain Connor on his Families Against Neuroblastoma (Fan) donations page, loves pizza, roast dinners and seedless green grapes, but has lost his appetite after undergoing his first stage of chemotherapy.

Mrs Power said: "Connor knows he is unwell but he thinks he’s got a monster in his tummy and we are trying to get rid of it.

"He’s never said the word cancer.

"It’s so hard and it’s going to get harder. I don’t want to lose him – I’m his nanny Mary."

Connor who has two sisters also enjoys playing computer games and often convinces Mary to play the Wii with him.

She said: "I’m terrible at the Wii and Connor gets frustrated and laughs at me – he’s a proper little boy."

Superhero-fan Connor will be hosting an optional fancy dress superhero fundraising event with a deejay and raffle at Barcadia bar in Kingston on Sunday, April 1 from 8pm.
