Black Sabbath star TONY IOMMI is winning his battle with cancer, according to his bandmate Geezer Butler.

The veteran rocker was diagnosed with lymphoma at the beginning of 2012, and has since been juggling his chemotherapy sessions with studio time and touring with the heavy metal band.

Iommi recently revealed his treatment will soon come to an end, and Butler has now confirmed his friend's cancer is in remission.

He tells Time Out Dubai, "Well Tony is probably healthier than everybody else now, after all the stuff they've done to him. He's really done well, he's definitely in remission now."

Butler goes on to hint the rockers may even consider heading back into the studio to record a follow-up to their U.S. chart-topping album 13, after frontman Ozzy Osbourne previously cast doubt on plans for a new record.

The bassist adds, "We've still got four tracks leftover from the album, so maybe we'll fill in the other four or five tracks and put out another album. If it's right. We wouldn't do it just for the sake of it, or the money or whatever. But yeah, maybe."
