Rachel Platten's Fight Song is powerful on its own, but when it's performed by a teen fighting cancer, it gets even more powerful.

Calysta Bevier is a sophomore at Otsego High School, just outside of Toledo, Ohio. She was diagnosed with Ovarian cancer when she was 15. As of August 28 she is in remission.

She made it her mission to pay it forward as much as she can, and she did!

Calysta performed this powerful rendition of Fight Song at a benefit for Thane Wooley, who is battling neuroblastoma. According to the information with the YouTube video, Thane is now in remission.
