Sharon is cancer-free, but Ozzy still worries

Sharon Osbourne is free of cancer after months of treatment, her rock star husband, Ozzy, said.

Ozzy Osbourne said he still feared his wife would become ill again and added that he was emotionally overwhelmed last year when her illness coincided with the success of their MTV reality show.

"She's got no cancer in her body now, they tell me, but there's always a chance of it coming back," Ozzy Osbourne told the music magazine Kerrang! "She's doing great, but I must confess that I'm still worried about her."

Sharon Osbourne, 50, announced last year that she was undergoing treatment for colon cancer, which she allowed cameras from "The Osbournes" to document. The hit reality series follows the daily misadventures of the couple and two of their three children, Jack and Kelly.

"With Sharon's cancer and the success of the TV show, I lost it last year, I just freaked out," the 54-year-old Osbourne said. "I think I had something like a nervous breakdown — my nervous system just imploded. This is all too much for me sometimes."
