OKLAHOMA CITY - Like many 12-year-old girls, Rachel Scott is a laughing, bundle of energy.
When she's not in school, Rachel spends her time at Native American dancing competitions, on the soccer field or cheering with her Little Axe squad.
Last year, her parents noticed something simply wasn't right.
"In August of 2015, she started having migraines, which we just thought were allergies," said Cindy Scott, Rachel's mother.
Her family said the energy she is known for suddenly disappeared.
"They were out shopping, and Rachel was just sitting on the floor, and she loves to shop and do those girl things and she just told her mom she couldn't make it," said Bryce Scott, Rachel's father.
That's when they took Rachel to the doctor, but that didn't give them any answers.
"Rachel was one of our challenging patients. We saw her in clinic about one month before we were able to diagnose her with leukemia," said Dr. Ashley Baker, a pediatric oncologist for the Jimmy Everest Center.
For the past nine months, Rachel has been undergoing aggressive chemotherapy.
The treatment has taken an effect on the nerves in her legs, forcing her to use a walker.
"The chemo has been hard on her. We've been at the hospital more than most people," Cindy said.
However, doctors hope the effects will disappear with time.
