When not hitting, Willie Perry Jr. works hard to beat deadly disease.
Perry, who goes by DJ Casper, is known for one of his hits, which is in fact a must-play for many celebrations in Chicago and around the world. But the life of the person behind the Cha Cha slide is almost not just smooth.
"I was poisoned for 24 months and at 22 [years old] I had a brain aneurysm," he shares.
also had retinas detached that led to major eye surgery, but it wasn't until a few years ago that the real battle for Perry began.
An animal or death situation has come a long and difficult time. Although sometimes it was a struggle, DJ Casper's cancer is already in remission and he says he's a changed person.  "Maybe in the process of going through the cancer situation, it was God's way of just slowing me down a little bit," he said. "But he keeps me here for some reason, definitely for some reason."
Perry said that he thinks this is part of the reason he is still here. He regularly comes to Stroger Cook County Hospital to meet with other men who are fighting similar health battles, such as cancer colleagues Renee Stewart and Alonzo Nichols.
Cancer Specialist Dr. Courtney Hollowell said that DJ Casper has a big difference. 'It happened to me' and serve as a resource for the next person to prevent them from happening, "says Dr. Hollowell.
This is also why you will often find DJ Casper at many cancer charities around town, like the recent Sista Strut in downtown Kroc in the south, where everyone tackled, of course, the "Cha Cha slide."

Believe it or not, this is the 20th anniversary of the Cha Cha slide and shows no signs of delay. You hear it in commercials, sports events and every wedding, gathering or any event.
DJ Casper hopes to break Guinness's record next year by making people around the world dance simultaneously to raise money for cancer research. He calls it Dime Drive and asks everyone to donate a penny.
Saturday, October 26, he holds the Dusties Music Convention at the Grand Ballroom in Cottage Grove. Part of that revenue will also go to cancer research.
