— -- Leah Still, the 5-year-old daughter of Houston Texans' defensive tackle Devon Still, has officially beaten cancer, and she's quick to share the credit.

"I think it's because my daddy made me [strong]," Leah Still told “Good Morning America co-anchor Robin Roberts in an exclusive interview.

The daddy-daughter powerhouse has shared their message of courage and strength, one selfie and fist-pump at a time ever since Leah was diagnosed with stage 4 pediatric cancer at the age of 4.

"I'm just thankful," Devon Still told Roberts. "It was definitely a long road traveled. We definitely feel blessed and thankful that we have the doctors and the people around us to help us through this battle."

Leah Still was diagnosed with stage 4 neuroblastoma in 2014. The disease develops from immature nerve cells found in several areas of the body and primarily affects children younger than 5, according to the Mayo clinic.

After treatment including chemotherapy and surgery, Leah received her final treatment last week, according to her dad's Twitter feed.

On Monday, Still, 26, posted on Twitter that Leah “really beat cancer,” and posted an image that put in numbers all that Leah has been through.

"[I feel] really good," Leah said on "GMA" this morning.

Leah began her cancer treatments when she was just 4 years old.

Last July, the girl's fight against cancer was recognized when she won the Jimmy V. Perseverance Award at ESPYs. Leah's dad accepted the award on her behalf.

"It was important to us, to be honest before my daughter was diagnosed with cancer, I didn't know too much about childhood cancer," Still said. "Just knowing I had the platform I knew I could reach a big audience and inform everybody what it's like for a family to deal with pediatric cancer."

As for his message to parents dealing with a child who is sick, Still said "don't give up."
