Last year, 11-year-old Alex was diagnosed with a rare bone cancer. He has battled the disease through chemotherapy and surgery and is currently in remission.

Through it all, his grandmother has admired his courage.

“I hope it (the skydive) shows him just how much we love him,” said Rebecca Byrom, who lost a daughter in a car accident years ago. “I lost a daughter years ago… I know what it’s like to lose a child.”

After her daughter’s death, Rebecca became a grief counselor. Now, she wants to do more for kids with cancer. Her skydive will help raise funds for childhood cancer research.
