BOSTON (CBS) – Sophie Fellows of Vermont plays the violin as beautifully as she smiles. “It’s a lot of fun,” Sophie laughs.

The 10-year-old has a lot to smile about having overcome a brain tumor this past year. “I feel great. I don’t feel sick at all,” Sophie said.

Exactly one year ago, Sophie fell sick during last year’s Christmas concert in Vermont. The headache that sent Sophie home turned out to be a brain tumor.

“She was battling a big brain tumor and she developed headaches and was supposed to play in this concert last year,” Dr. Liliana Goumnerova of Dana-Farber/Boston Children’s Hospital said.

Sophie underwent brain surgery at Dana Farber/Boston Children’s Hospital Cancer and Blood Disorders Center.

“It’s been pretty tough,” Sophie said. For the past year Sophie and her family have been traveling from Vermont to the hospital.

After surgery her family was not sure if she was going to be able to play again. “At that time there was uncertainty not knowing if this was a tumor we could take care of,” Dr. Goumnerova said.

Now one year later, Sophie is in a different place. She’s in the clear and playing better than ever. “I just want to thank Boston Children’s Hospital and Dana- Farber,” Sophie’s dad Chad fellows said.

On Friday, Sophie took center stage alongside her doctor who performed her surgery to play at a holiday concert at the hospital. “I have butterflies in my stomach,” Sophie said.

Sophie’s parents listened with great joy and humility. “I’m just thrilled. The highlight was playing with her surgeon,” Sophie’s mom, Aimee Fellows said.
