12-year-old Drew Beiter, of Lockport, rang the Victory Bell at Roswell Park on Monday afternoon.
"I hope that it never comes back and I'm just set free," Drew said.
Drew was diagnosed with Leukemia on October 2, 2014. The seventh grader rang the bell at Roswell, just as others do when they finish a treatment or receive good news.
"It's been three years and two months in the making," Krista Beiter, Drew's mother, said. "We are excited to reach this point."
It was three years ago when 7 Eyewitness News first introduced this story, shortly after his diagnosis.
To lift Drew's spirits for the holidays, his great Aunt and a group of retired teachers sent him Christmas cards early on in his treatments in 2014.
Word of Drew's story spread from there and several cards turned into dozens... then hundreds... eventually reaching more than a thousand!
Drew received 1,500 cards that Christmas and even today they still mean so much.
"I was pulling out the Christmas decorations this year and I went through the box. It's amazing. He still gets some cards from people every year that started in 2014, and every year they send them," Krista said.
Now the Beiter's are looking forward and for the first time in years, Drew can focus on being a kid.
"So I can focus on hockey for the next few years now that this is put out of my way," Drew said.
