The daughter of former Cincinnati Bengals player Devon Still just celebrated a big milestone: being cancer free for one year.

Leah Still was diagnosed with stage 4 neuroblastoma in 2015 at age 4. 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.

Devon Still took to social media today to celebrate his daughter's "second birthday."

"I want to wish a Happy (2nd) Birthday to my baby, Leah," Still wrote on Instagram. "Today, March 25th, marks a year of her being in remission! A day she was given a second chance at life."
