Campbell is officially in remission for the second time and will be receiving the treatment in hopes that it will prevent the cancer from returning. Elliot told Las Vegas radio station KOMP 92.3's '92 Minutes of Hair With Mel' show (via Loudwire), "Vivian, for the second time, is now in remission.

"The first time we were told he was in remission and he was, but it didn't take. It didn't stay; it came back. But this time, through clever management with his doctors, they were able to monitor him through the whole tour, so he could do the tour with KISS this summer."

Elliot went on to say, "As we speak, he's getting ready to go in to have stem-cell surgery, which will hopefully get rid of this thing once and for all. So, up until Christmas, he's gonna be kind of out of action, because once they start on this, they have to keep him so locked down and away from germs and stuff.

"I think anybody visiting him has to put on one of those nuclear suits. He'll be locked away and he'll be the boy in the bubble, but he's very confident that he can do this and his spirits are great."

There is no word is Vivian will be joining the band this Sunday when they perform the pregame show at the NFL game between The Oakland Raiders and the Miami Dolphins in London.

Elliott had this to say about the show, "Having most recently visited Wembley in May to watch Sheffield United in the FA Cup semi-final, I know what the atmosphere in the ground is like for 'our' football so I'm really looking forward to performing there before the NFL game and of course soaking up the excitement of the actual match. I can't wait!"
