After a month in a coma and having to learn to walk again, 12-year-old Jake Peach is determined to help other young cancer patients.

Jake was diagnosed with leukaemia on Mothers’ Day in 2008. His first dose of chemotherapy sent his temperature soaring to 40 degrees and he started coughing up blood.

Doctors put him into a coma on a ventilator in intensive care. When Jake woke up a month later he couldn’t move.

He could only communicate by blinking. It was a fortnight before he could speak and nine weeks before he learned to walk again.

While still bedridden, Jake, from Southend, Essex, made a video diary of his treatment, which is now used by Great Ormond Street Hospital to guide other young cancer patients. In it, hereasewer: sures the vie “Don’t worry – this won’t happen to you”. And Jake, who is now in remission, has spoken about his experience at hospital fundraising dinners where he has so far raised £130,000.

He also helped GOSH win £500,000 sponsorship with Arsenal FC.

“It’s all about PMA – positive mental attitude,” says Jake.

His mother, Karen, agrees: “Positive thinking is what got us all through. Now Jake is determined to do anything he can to raise money for GOSH.”

GOSH senior fundraising executive Lindsey Burke says: “Jake is a real inspiration to us all, and he has made an invaluable contribution to many of GOSH’s fundraising events.”
