What would you do if your child was diagnosed with a fatal disease? This week's Everyday Hero turned from fighting to help her child to helping other children fight cancer.

Amber Larkin has albums filled with happy pictures of her son, Noah.

"He was this old soul," she said. "Anybody that met him was just floored by this child."

Amber remembers exactly when her life, along with then-6-year-old Noah's, were turned upside down when a hospital visit for a sudden illness led to brain scans.

"I turn the corner, and I see a doctor standing there with a silhouette on a computer monitor of my son's head, and a golf ball sized tumor in the center of it," Amber recalled.

Then came surgery and harsh radiation, but during remission there were happy times for the ray of light she calls "My Jedi Noah."

"People just came out and said, 'What can we do? How can we help you?' And as much joy as we could pack in, we absolutely did," Amber said.

Amber was inspired to launch the Noah's Light Foundation to raise money for pediatric cancer research and back a promising experimental therapy at the University of Texas M.D. Anderson Cancer Center. But this new opportunity advancing hope, or "Noah protocol," could not be delivered in time.

"On May 29, 2012, my Noah was not the first one to receive the Noah protocol," Amber said. "Instead he received his wings, and he was free from cancer forever."

But Noah's actual cancer cells did help prove the treatment can work. Now, by harnessing NK or "natural killer" cells to destroy cancer, the hope is that, one day, many forms of the disease be cured.

"I am so excited, because we know some of the families that will be my Noah, the first one to do this, and that will be an amazing day for me," Amber said.

The University of Texas M.D. Anderson Cancer Center has received approval from the Food and Drug Administration to treat its very first group of pediatric patients with the "Noah protocol" later in February.
