A Colorado teen fighting brain cancer realized his dream when he was sworn in as a honorary police sergeant by the Lakewood Police Department, KUSA reported.

Trevor Kling was diagnosed with anaplastic astrocytoma two years ago. The 13-year-old has endured 14 months of chemotherapy and 34 radiation treatments.

“Every day I had to go to treatment after school,” Kling told KUSA.

Despite the treatments and the pain that came with them, Kling missed only one day of school and maintained a 3.87 grade-point average.

“We think we have a difficult time, things are tough for us or tough in this job and in this profession,” Lakewood police Chief Dan McCasky told KUSA. “When we look at a young man like Trevor and we see his courage and commitment, it really kind of invigorates all of us and makes us realize how precious life is and really, we value his courage and dedication and commitment too.”

Kling said he was inspired by watching policemen in action.

“I saw a show on police, and I wanted to do what they were doing,” he told KUSA. “Helping out the state of Colorado.”

As Kling continues his battle against the aggressive cancer, one thought keeps him motivated.

"Hope that I'll get better," he told KUSA.
