If you know someone who's battling cancer, share this video with them. Her name is Lily Anderson, she's 10-years-old and she's fighting the disease.
Anderson sang the Star Spangled Banner at Thursday night's Braves vs. Pirates game at Turner Field in Atlanta, Georgia.
Officials say she got the longest standing ovation of the season and one of the longest in recent memory.
Anderson, sporting a flower-patterned bandana on her head, is undergoing treatment for a relapse of Nueroblastoma.
She sang the National Anthem on behalf of the Rally Foundation for Childhood Cancer Research.
