BUFFALO, N.Y. (WIVB) – An 8-year-old 49ers fan, who is a cancer survivor, was shoved by a Buffalo Bills fan at Sunday's game, causing her to fall from her seat. Mia DeCamilla's family said she was not physically hurt during the altercation, but was emotionally shaken, causing them to leave her first-ever NFL game early. Mia currently lives in Rochester, N.Y., however, she became a big 49ers fan because of her father. “Me and my dad in the hospital, we'll watch football together, and then when I come home … I will sit down and just relax and watch football all day, that's what I like and how I made my team,” Mia said. MLB commissioner says there’s ‘buzz’ about a Golden At-Bat rule. What is it? Mia has battled and beaten liver cancer twice after relapsing in May of last year. She has also worked to raise money for other young cancer warriors. Mia DeCamilla is seen at her first NFL game on Sunday, Dec. 1. (Courtesy the DeCamilla family) Mia braved her first cold and snowy NFL game with a smile, holding an "I beat cancer" sign with pride. “In the car, when we were driving there, I was saying like, 'Are we there yet?' I was too excited. I was full of energy,” Mia said. The fun night was cut short after the family said a drunk Bills fan pushed Mia down the stairs in unshoveled section 312. “He said, 'I'm going to push through all these Niner fans," said Mia’s father Mike DeCamilla. "So, he actually bumped me and my son a little bit and then got past me and pushed her, almost slid off the stairs." The family was so uncomfortable, they left the game early. “The guy purposely walked through and was pushing through people," Mike DeCamilla said. "I get that it's busy and hectic, but he had to be 6 foot, and she is less than 100 pounds." The story caught the eye of former NFL player Antonio Brown, who is planning to FaceTime Mia and raise awareness of her battle.Social media users have since called on Bills fans to "do better" while others said the incident isn't a reflection of the Bills Mafia. The Bills organization makes a point to ensure that any home game is welcoming to both Buffalo fans and fans of the opposing team. But Mia said she won't be back at Highmark Stadium anytime soon. “We don't want to go back because I felt uncomfortable and I just don't feel ready to go there anymore,” Mia said. Why do these NFL players wear ‘old-style’ helmets? Mia and her father added that they hope what happened raises awareness to what some kids are going through. “I know that there's competitiveness and whatnot, but there's a point where it's a family event,” Mike DeCamilla said. “I just want to help and not be rude," Mia said. "I'm just there to be a nice girl and just have fun." As of Monday night, over $22,000 has been raised for a GoFundMe helping to support Mia's battle.
