4-month-old baby beats brain cancer, rings bell with mom's help in emotional video

Lillian Grace Borden was born Sept. 5, 2019 and seemed like a perfectly healthy newborn.

"She was not distressed at birth, we held her, she cried, we cried, all was right with the world," her mother, Leann Borden, told "Good Morning America."

But a nurse noticed something wasn't quite right.

"Lily wasn’t moving her limbs quite right," Leann said.

An MRI was done "and there it was, an ominous spot on her brain stem."

Immediately, the Reno, Nevada family was flown to UCSF Oakland Children’s hospital.

Lily was soon diagnosed with a stage 3/4 Glioma brain tumor.

She started treatment on Oct. 2 and, incredibly, the tumor that had traveled down her spinal cord was gone when another MRI was done on Nov. 13, according to a GoFundMe which documented every stage of Lily's journey.

Lily, almost 5 months old, was officially diagnosed as cancer free on Jan. 25.

Leann helped Lily ring the bell as she left the hospital in an emotional video:

"We are so grateful to everyone here for everything you did," Leann said in the video. "We would have lost everything. I've never met such amazing people in my whole life."
