Little Jimmy Spagnolo couldnt contain his joy after finishing his chemotherapy treatment.

The brave 6-year-old, who was diagnosed with an inoperable brain tumor when he was just 4 months old, jumped up and down and wiggled his body all around after ringing a bell at the Childrens Hospital of Pittsburgh in Pennsylvania on Friday.

His ridiculously adorable reaction was recorded, and the video is now going viral. That was our battle cry for the year for this round of treatment, Jimmys father, Jim, told CBS Pittsburgh. It was really special.

Watch the full video here:

Hospital patients traditionally ring the bell after reaching treatment milestones or becoming cancer-free, with staff saying its ringing can signify the sound of tears, strength, fear, courage, doubt, satisfaction, relief and happiness all coming through as one as people around them cheer this accomplishment.

So far, Jimmy has undergone four rounds of treatment. He still has a tumor, but doctors say it is much smaller than it once was. They are hopeful he can live with it, if it doesnt grow again.
