At 11 years old he was diagnosed with a rare form of bone cancer called Ewing's Sarcoma.
Only three children out of a million are diagnosed with this cancer each year.
It started as an intense pain in his right foot. The pain wouldn't go away.
His mother, Bianca Trujillo, took him to the hospital where he was misdiagnosed twice.
Then she got the news she feared.
"The doctors came in and said, 'We're going to tell you now, that the type of cancer he has, he has a 50-50 chance and he might not make it through this,'" Trujillo said. "It scared me. [I'm] thinking he looks fine. He's got a bump on his foot. That's all."
"I was in shock," Miranda said. "I didn't know how I was feeling. I had mixed emotions."
He started radiation and chemotherapy immediately. Over the next few months he had several biopsies and surgeries. But the worst was yet to come.
"One day they came and said 'We are going to take off a chunk of his foot,'" Trujillo said.
The bone cancer was spreading and doctors had no choice but to cut off a portion of Dominic's foot.
"My very first question to them was, 'When am I going to play football?'" Miranda said.
Miranda's passion for football started when he was just a toddler.
At seven years old, he started playing and played up until the day before he was diagnosed.
Dominic went through 19 rounds of chemo, four surgeries and an amputation.
In October 2011, he and his family finally got the news that he was cancer free. Before his last round of chemo was even completed, Dominic hit the gridiron once again.
"He said 'I'm going to play football,'" Trujillo said. "I thought, 'Oh my goodness, this kid is going to kill me.' He went out there and his foot gave him a heck of a time. He still had an open wound. It was oozing."
"I wasn't going to be just laying there crying," Miranda said.
Miranda had to relearn how to walk, run and even balance again.
"I see him game after game, practice after practice trying to earn his spot back and show them that he can do it," Trujillo said.
Even though life may not be fair, perhaps there's a reason 11-year-old Dominic Miranda was chosen to be inspiration to all.
"Most people never get to meet their heroes and I gave birth to mine," Trujillo said.
"I can show people what I can do without cancer slowing me down," Miranda said.
Miranda has been cancer free now for almost a year. The chance of his cancer returning is very small.
September is National Childhood Cancer Awareness month. Every year, more than 10,000 children under the age of 15 are diagnosed with cancer.
