A brave five-year-old boy from Clapham who has beaten kidney cancer was a special guest at Cancer Research UK’s awards party in central London.

Karos Rasoul, who was diagnosed with a Wilms’ tumour when he was just two, was one of 20 children at the charity’s Kids and Teens Star Awards.

The courageous little boy has come a long way since his diagnosis, and his dad Sabah has spoken openly about the challenging times.

He said: “We knew he wasn’t well. He lost his appetite, had night sweats, lost his balance, was vomiting bile and his tummy had become hard.

“We were so scared and all we wanted was to know if he had a chance to live.

“He’s been so brave throughout his illness that he’s been an inspiration to the whole family.

“When he was in a lot of pain in hospital, he kept saying there was a naughty dinosaur inside his tummy, so that’s what we called it after that. We told him the dinosaur was out once he had the operation.

“As a parent, the hardest part was watching him in pain and not being able to do more to help.

“He’s been so brave throughout his illness that he’s been an inspiration to the whole family.”

At one point, the Wilms’ tumour had spread to his lungs.

Karos had major surgery to remove the tumour and his kidney, followed by two weeks of radio therapy and months of chemotherapy.

But his dad said the family feels “normal” again and celebrated turning five this year with a “huge” superhero cake.

He’s also in reception and, while he still has regular scans, he is doing well and plays with both his brother Keyan and sister Karleen.

Cancer Research UK Kids and Teens Star Awards are part of the charity’s wider campaign which aims to raise funds for research across the UK.

This is in a bid to find “new, better and kinder” treatments for children and young people who have been diagnosed with cancer.

Lynn Daly, Cancer Research UK Kids and Teens spokeswoman for London, said: “It’s a privilege to be able to recognise the strength of youngsters like Karos who have been through so much at such a young age. He is a true ‘star’.

“Cancer can have a major impact on children, so it was fantastic to see Karos enjoying the party.

“Our mission is to save the lives of more children and young people diagnosed with cancer in London and across the UK, and to reduce side effects caused by treatment, by finding new, better and kinder treatments.

“It was a total joy to meet Karos and his family – we hope they’ve had a fantastic time and created some amazing memories together!”
