A TEENAGER who is battling a brain tumour helped show Great British Bake Off star Mel Giedroyc the difference Children in Need funding can make.

Jenna Niblock, 13, and her family featured on a BBC1 documentary on Monday night which showed how this year’s Children In Need single – a celebrity choir’s version of Wake Me Up by Avicii – was made.

Diagnosed with a low-grade ganglioglioma three years ago, Jenna, from Presteigne, had surgery at Birmingham Children’s Hospital to remove some of the tumour, and has MRI scans every four to six months to monitor her progress.

Like many around the country, Jenna’s family is supported by a children and families worker, a role that benefits directly from Children In Need money.

Along with her mum and dad, Carol and Chris, and her two sisters, Ellie, 15, and Ashlin, eight, Jenna joined Mel on a tour of Wookey Hole caves in Somerset.

“It was a brilliant day and great fun meeting Mel,” said Jenna, a pupil at Newtown High School’s Presteigne campus.

“She was so friendly and I felt famous, too!”

An avid Harry Potter fan, Jenna thought the caverns reminded her of Hogwarts, while Mel told the cameras that the smell reminded her of Paul Hollywood socks.

Jenna and her family are supported by The Brain Tumour Charity, who, as part of their work with families, organise days out when those battling brain tumours can relax around people who understand what they are going through.

Jenna’s mum said: “It is so supportive and reassuring meeting other families through The BrainTumour Charity.

“At the school gates or work, you put on a smile. But at the charity’s family days, you can just be yourself and talk to other people who ‘get’ it.”
