Brandon is now seven-years-old.

Three years ago, he was diagnosed with Acute Lymphoblastic Leukemia.

Cancer at four-years-old.

For three years, Brandon battled cancer.  He did chemotherapy and had to deal with various infections related to the treatment.

Brandon is now cancer free.

To celebrate his victory, he and his family released the video below.  It features Brandon and Tom Petty's I Won't Back Down.  Petty himself gave Brandon the blessing to use his song for this inspirational message.

The video was debuted earlier in November and helped raise $20,000 for families who are dealing with cancer.
