Every year in the United States, approximately 10,400 children under age 15 will be diagnosed with cancer, and roughly 1,545 children will die from the disease. If you've ever visited the cancer ward in a children's hospital, you know how heartbreaking it is to watch a child suffer from this (and other) terrible illnesses. But there's always hope, right?

Chris Rumble -- a 22-year-old cancer patient himself -- invoked the help of his fellow patients in his wing at Seattle Children's Hospital to spread some of that hope throughout their ward. He and several adorable, courageous kids created this lip-dub video of themselves mouthing along to Kelly Clarkson's hit song 'Stronger.'

"I’m everyone’s big brother and I have a lot of friends here at Seattle Children’s," Chris explains. “I wanted to make a video to send back to my [soccer] team and I thought what better way to do it then with the kids on my floor.”

Warning to our readers: This video is guaranteed to give you goosebumps, and it might even make you cry. Each of the children featured in the video have been diagnosed with cancer, but it's clear they believe that they will make it through -- and that they'll be stronger people for it. With Clarkson's hit song playing in the background, these brave youngsters learned the lyrics, sang along and danced for the camera. The result? A montage of hope in a place that is often full of sadness.

Thanks to Seattle Children's Hospital's outreach, Chris has definitely taken the video trend by storm. The hospital's YouTube channel has more than 400 videos, including helpful advice for patients, interviews with volunteers and an in-depth look at what it's like to be a cancer patient.

The cancer and blood disorders center at SCH is equipped with award-winning researchers and doctors. Among all pediatric oncology centers in the nation, this hospital is consistently among the top five for patient enrollment in clinical trials. Not surprisingly, the survival rate for children with cancer is actually higher at SCH than the national average.

Making the 'Stronger' video gave patients and opportunity to move around, dance, sing and just take their minds off of their illness for a short while. Special thanks to Kelly Clarkson, who not only brings hope to young people who dream of being famous singers, but to kids with high hopes of living a full life, too.
