Though Millie McColl is only three years old, she already has been going through treatment for an aggressive form of cancer for much of her life. While being treated at Glasgow's New Royal Hospital For Sick Children in Scotland, some of her nurses helped her out in the cutest way.
McColl's cancer neuroblastoma is a disease of the nervous system that typically only occurs in kids 10 and under. McColl's treatment, though promising, is long and exhausting.
McColl's mother explained on a crowdfunding page for her daughter that there's around an 80% chance the cancer will return, so they're fundraising for preventative treatment that only takes place in the U.S.
To lift McColl's spirits, the Les Hoey Dreammaker Foundation bought her a karaoke machine. On Friday, Nov. 6, McColl's mother captured a heartwarming performance of "Let It Go" from "Frozen" where Millie's nurses help her sing and provide props and backup dancing. The video has gone viral, with over 420,000 views since it was posted.
