OKLAHOMA CITY – These days, 10-year-old Luke Jackson enjoys racing down the sidewalk.

So much so, he even created a piece of artwork about his passion.

“So, that’s me,” Luke said. “I’m riding my scooter, because I love riding scooters. It’s one of my favorite things.”

For Luke, being on a scooter is pure pleasure.

“I usually do it 5 million times a week,” he exaggerates.

The truth is Luke spends more time than he’d like at Jimmy Everest Center for Cancer.

For the past two years, Luke has been battling a tumor that sits inside his optic nerve.

“This is a rare optic nerve tumor, but it has a good cure rate,” said Dr. Rikin Shah.

A brain scan shows Luke’s tumor has shrunk in half, compared to the scan he first took two years ago.

Luke’s mother, Melissa Jackson, took him to the doctor when she noticed something strange happening with his eye.

“He had a little bit of a lazy eye,” Melissa said. “It started shaking a bit, and so she wanted to take an MRI to eliminate the worst possibility first.”

However, doctors found a malignant tumor.

Luke has already been through two years of chemotherapy and has two more years ahead of him.

If it were surgically removed, Luke would go blind.

As it stands, doctors don’t believe the tumor will ever completely go away.

“The plan and idea is to keep the tumor at bay as much as possible. There’s a huge team of people keeping it in check,” Melissa said. “The good news is that Luke can stay in school, every weekend he’s in church. He likes to play with his brother and his friends in the neighborhood.”

“God’s with me, and I get right through it and act tough,” Luke said.
