Devon Still and his daughter Leah may have just won the biggest battle of their lives. Leah is battling a form of pediatric cancer called neuroblastoma. On Thursday morning, Leah faced one of her biggest battles yet with the dreaded disease, and it could be the final one.

Following several rounds of chemotherapy, on Thursday, the 4-year-old Leah underwent surgery to have a tumor removed from her abdomen.

She's now out of surgery, and Still posted this message on his Instagram account:

After a 5hr 50min surgery the surgeon was able to remove ALL of her tumor and all of her lymph nodes and her right adrenal gland where it all started from...best news I've received in a long time #PrayForLeah #GodIsGood #ThanksForYourSupport

The road for both Still and Leah to this point has been a long and winding one to say the least. Still was released by the Bengals before the season but re-signed to the practice squad so he could provide healthcare for Leah.

The team then brought him back up to the active roster. The Bengals also announced they would donate proceeds from sales of Still's jersey to help battle pediatric cancer, and Saints coach Sean Payton even decided to buy 100 of them.

Hopefully, the worst is behind Leah, and she can now slowly begin living a normal, 4-year-old life full of joy and happiness. That said, it's clear Leah was going to live that way anyhow, even while dealing with the disease that's claimed so many lives.

Thankfully, it doesn't look like hers will be one of them.
