CNN - 11 years ago, the Tyson family seemed to have it all. Nicole and Scott Tyson had just bought land in Sharpsburg, Georgia, to build their dream home. They envisioned starting a small farm, with a place for their kids to play. Less than a month later, their world changed as they rushed their son Mason to the emergency room on his 4th birthday. "We had felt the lump in his abdomen, which we later found out was a tumor," Nicole said.
