MOUNT LAUREL, N.J. (CBS) — A South Jersey firefighter is used to suiting up and putting out fires, rushing in to save lives. Now, he’s helping save lives in a much different way. It’s a mission inspired by a battle of his own.

“The worst day of my life, hands down. Three kids. What to do?” he said.

“As they put it, cured, which is a good thing, hands down. But I gotta take certain pills the rest of my life,” he said.

“It’s awful that we’ve been through it, but let’s make lemonade out of this now. Let’s make it better for other people,” Theresa said.

This Father’s Day will be Joe’s third being cancer-free.

“We love him, we’re so proud of him. He would move the world for us and he’s everything to us,” Theresa said.
