6-year-old Jimmy Spagnolo is on top of the world after finishing his last chemotherapy treatment and this happy dance proves it. Dancing has really been a part of his treatment throughout the 6 years he's been fighting cancer. His mother says he was diagnosed with a brain tumor when he was just 4 months-old. That's when he started going for IV chemo treatments and his parents danced with him to keep his spirits up. Since then, he's been dancing every time he leaves a treatment session.
