Must-see video: Cancer patient, Chris Rumble, creates an inspirational message of hope - The 22-year-old created a new take on Kelly Clarkson's hit single "Stronger", and it has become an internet sensation

Thirty five days ago, Chris Rumble’s life changed dramatically.

After feeling unwell, the 22-year-old was rushed to hospital when doctors discovered that 95-percent of his blood was full of leukemia cells. It may have seemed like a death sentence, but for Rumble, he has now created a powerful message of hope .

While at Seattle Children’s Hospital on the hem-oncology floor, Rumble spent Saturday filming fellow patients, doctors and nurses and created his own version of Kelly Clarkson’s hit song, “Stronger.”

In the clip, patients and staff can be seen singing and holding signs that read “Hope” and “Fighter,”.

“It was kind of like a party,” said Rumble, who filmed the video during the day, stayed up late Saturday night and posted it on YouTube early Sunday.“It wasn’t a typical day at all.”

However, since posting the clip three days ago, the video has gone on to become an internet sensation, amassing over 250,000 hits and sending out a powerful message of the resilience of the human spirit.

Simply making the video lifted the spirits of many of the children on the floor, said Brittany Skinner, 26, a pediatric hematology oncology nurse who is shown dancing and singing.

“It gave them something to shine through, I guess,” she said. “Like the song said, ‘What doesn’t kill you makes you stronger.’”

And Kelly Clarkson herself, has given her seal of approval to the clip, tweeting: “Oh my goodness y’all have to see this! It’s beautiful! I can’t wait to visit these kids and nurses!”

For Rumble, Friday will be another life-changing moment, as he will learn whether his cancer is in remission.
