#StephensStory: David Cameron Calls Cancer Teen 'Amazing Inspiration' For Raising £3.4m

The Prime Minister has paid a private visit to a teenage cancer patient who has raised more than £3 million for charity while battling the disease.

David Cameron dropped in to see Stephen Sutton at Birmingham's Queen Elizabeth Hospital this morning, spending around 15 minutes with the 19-year-old.

During the meeting, Stephen, whose fund-raising for the Teenage Cancer Trust has won backing from people around the world, posed for pictures alongside the Prime Minister, his mother Jane and the consultant treating him.

Following the visit, Cameron described Stephen, who has used Facebook and YouTube to chronicle his battle against multiple tumours, as an "amazing" inspiration to others.

Speaking ahead of an event to launch his party's local and European election campaign, Cameron told the Birmingham Mail: "He's amazing, just an inspiration.

"Anyone who watches that video on YouTube just can't help but be impressed by his bravery and courage but also his incredible warmth and passion for life.

"It really is extraordinary."

Cameron added: "He's also got a great sense of humour, a great sense of fun, his bucket list is extraordinary."

Stephen, from Burntwood, Staffordshire has so far raised £3.4 million after Stephen's Story, a film about his bucket list, was posted online.

Cameron gave Stephen a letter which read: "Dear Stephen, I wanted to write to say how inspiring it has been to watch the progress of your campaign. The way you have responded to such a difficult diagnosis is incredible; your bravery and positive attitude is truly humbling.

"You have caught the attention of people around the world and helped raise an enormous amount of money to support other teenage cancer sufferers. I understand that your postbag is growing by the day.

"You have my admiration and gratitude for all that you have achieved, Samantha joins me in sending you a 'big thumbs up'."
