NEW YORK (PIX11)-- It was a day of fun for boxing champ Danny Jacobs and his five-year-old son.
It was also a day of reflection.
Jacobs visited the New York City Ronald McDonald House, which hosts families from around the world whose kids are battling cancer.
"The House is a special place for our families," Natalie Grieves, spokeswoman for the NYC Ronald McDonald House said. "We provide a place where the kids can be kids and the families can relax after a long day of treatments."
"It's a loving home feeling and that's what you want," Jacobs said. "Especially when you battling kids with cancer.:
This is a fight for life-- Jacobs knows too well.
"I had osteosarcoma, which is a very rare bone cancer," Jacobs said. "And the tumor, eventually it cracked my spine to leave me partially paralyzed."
That was only two years ago, but he beat it just like he does with his opponents in the ring.
“What I didn’t realize was when I came out of the hospital the impact that it would have on so many other survivors," Jacobs said.
Survivors like Cody Brynes, a 19-year-old visitor at the Ronald McDonald House.
Last weekend, Cody watched as Danny "the Miracle" Jacobs became the first cancer survivor ever to win a world title.
"I used to ask why is all this is happening to me and you know now with touching so many lives I realized this is my purpose, this is my cause." Jacobs said.
