Teen Escorts Terminally Ill Mom to High School Prom

"That was the most beautiful I think I've ever seen her," Dylan Huffaker said.

— -- An Idaho teen escorted his mom to prom last month, after she feared she'll miss his future wedding day.

Kerry Huffaker of Twin Falls, Idaho, was diagnosed with stage 4 brain cancer on Feb. 18 with a nine to 20-month prognosis. So, her son Dylan, 17, brought her as his date to the Canyon Ridge High School prom on April 30.

"That was the most beautiful I think I've ever seen her," Dylan Huffaker told ABC News today. "I thought about it and I can look back after years and years and remember who I went to prom with. I'll know it was someone I loved who meant something to me."

"I was taken by surprise, that's for sure," Kerry told ABC News. "I try not to focus too much on the future. I try to live today as best as I can, but [thought], 'Who's going to dance with my son when the mom is supposed to dance with the groom at his wedding day?'"

She added: "My reaction was, 'You don't want to go to prom with your old, bald mom. You'll be embarrassed.' And he said,'No I won't. I'll have the prettiest date there.'"

The prom was held in Dylan's high school gym on a Saturday.

"[The D.J.] cleared the dance floor and let us dance the first half, just me and my mom," Dylan said. "I put her through 17 years of hard times, so it's worth it to take her to prom. I love that my mom is as caring as she is. No matter what your going through, she's willing to help -- no matter what hard times she's facing."
