4-Year-Old Battling Cancer Dresses Up As Herself for School 'Superhero Day

Superhero Josie Kimberlin

A 4-year-old girl showed up to school last week dressed as herself for 'Superhero Day,' as she continues to fight her two-year battle with cancer.

"In my eyes she's been so brave through everything and for her to feel like that shes's going to make it through, that means the world to me," mom Alyssa Butler of Kelso, Missouri told ABC News. "When I explained to her that she was my hero, she was so happy and excited."

Butler said her daughter Josie was diagnosed with acute lymphoblastic leukemia on June 6, 2013. 

Butler decorated the cape for Josie's costume, writing 'Super Josie--Destroying Cancer One Day at a Time.'

"I read it to her and she absolutely adored it," she said. "She was running around smiling. She was really proud of it."

Butler said Josie's teachers loved her self-made superhero costume.

So touching.

She is indeed a true superhero.. Much love from us, and we pray you kick cancer's butt real good.
